Implement the "gdb_signal_to/from_target" gdbarch methods for FreeBSD.
This fixes failures in the gdb.base/exitsignal.exp test.
gdb/ChangeLog:
PR gdb/23093
* gdb/fbsd-tdep.c (fbsd_gdb_signal_from_target)
(fbsd_gdb_signal_to_target): New.
(fbsd_init_abi): Install gdbarch "signal_from_target" and
"signal_to_target" methods.
