res_musiconhold: Add option to loop last file.

Adds the loop_last option to res_musiconhold,
which allows the last audio file in the directory
to be looped perpetually once reached, rather than
circling back to the beginning again.

Resolves: #122
ASTERISK-30462

UserNote: The loop_last option in musiconhold.conf now
allows the last file in the directory to be looped once reached.
