Rollup merge of rust-lang#132232 - asomers:fbsd-13.4, r=Mark-Simulacrum

CI: build FreeBSD artifacts on FreeBSD 13.4

13.2 is EoL, and 13.3 will be EoL too in about 2 months.  Plus, both suffer from a bug in LLVM's libunwind.  It causes a segfault inside of std::backtrace::Backtrace::capture().

Fixes rust-lang#132185

cc `@ehuss` .  before you can do the trybuild, you'll also have to download new FreeBSD 13.4 base.txz images and place them in https://ci-mirrors.rust-lang.org/rustc , then update this PR with the correct file names.
