treewide: Packaging overhaul

Running phrog as a proper greeter session under greetd is a rather
complex and delicate endeavour. It also differs in many subtle ways
across different distros.

So instead of trying to document this stuff, or provide examples, let's
just distribute fully-formed prescriptive configs for each distro. For
now this means Fedora and Alpine since I have the most familiarity with
them (and use them on a regular basis), but I want to pull Debian in
eventually, too.

On Alpine, the init.d script already has support for easily specifying a
separate config file, so we don't need to ship a separate init script.
So all a user needs to do here is drop a cfgfile= into their
/etc/conf.d/greetd.

On Fedora, a distinct phrog.service unit is introduced which conflicts
with greetd's default greetd.service. For now, the only difference this
service has to the default is a --config arg. Later, when we support
Plymouth flicker-free boot, it will also Conflict=plymouth-quit.service
to take over that process (just like gdm.service does).

This commit also introduces the use of gnome-session to run the phrog
shell. This ensures auxiliary services like the gsd-* daemons and an OSK
are present.

Since gnome-session is in place, we also use that to spawn phrog itself,
so a .desktop file is now shipped to handle that.

Rather than shipping a phrog-session wrapper script like Phosh does, we
just embed the necessary incantation into the greetd-phrog.toml, since
this is quite distro-specific a distinct copy of this file is maintained
in distro/<distro>. The example-config/phrog-session introduced recently
is deleted in favour of this new setup.

(Another reason why the phrog-session wrapper isn't desirable here is
that one cannot/shouldn't run the phrog greeter independently, as it
expectsto run under greetd and be supplied a GREETD_SOCK)

The README is updated and cleaned up a bit to reflect this work.

For now, I'm not interested in trying to explain how to get phrog
working on an unsupported distro, since a properly working setup
requires too many auxiliary bits (session + desktop files) and relies on
too many things that differ wildly across every. frigging. distro.
Instead, the README just directs interested folks to get in touch.

-`phrog` is a [greetd][] "greeter". To use it, make sure your `/etc/greetd/config.toml` looks like this:
+# Configure greetd to run phrog:
+cat >> /etc/conf.d/greetd <<HERE
+cfgfile="/etc/greetd/config.toml
+HERE
 
+rc-update add greetd
 ```
-[default_session]
-command = "systemd-cat --identifier=phrog phrog"

-Then run greetd however your distro prefers you to, see the
-[example-config](./example-config) directory for an example greetd config and
-startup script that launches greetd in a way suitable for mobile use.
 
-You can also test it outside greetd, nested in your favourite Wayland desktop environment:
