MMapPath::Vsys for /SYSV pseudo files

[tatref]

Shared memory segments are displayed as /SYSV<key> (deleted) in /proc/<pid>/maps or smaps, where key is related to the key field in ipcs -m or cat /proc/sysvipc/shm

Examples:

$ sudo cat /proc/*/maps | grep /SYSV
7ff8ac138000-7ff8ac1b8000 rw-s 00000000 00:01 4                          /SYSV00000000 (deleted)
9f800000-9ff47000 rw-s 00000000 00:01 7                                  /SYSV00000000 (deleted)
a0000000-a0006000 rw-s 00000000 00:01 8                                  /SYSVba5bd51c (deleted)

$ ipcs -m

This commits adds a variant in the MMapPath enum that contains a i32 (the key parsed from hex)
