bsd-user/signal.c: Only copy the _capsicum for FreeBSD_version > 1400026

Browse source 
The capsicum signal stuff is new with FreeBSD 14, rev 1400026, so only
define QEMU_SI_CAPSICUM there. Only copy _capsicum when QEMU_SI_CAPSICUM
is defined. Default to no info being passed for signals we make no guess
about.
