Support 'info proc files' on live FreeBSD processes.
This walks the list of struct kinfo_file objects returned by a call to
kinfo_getfile outputting a description of each open file descriptor.
gdb/ChangeLog:
* fbsd-nat.c (fbsd_nat_target::info_proc): List open file
descriptors for IP_FILES and IP_ALL.
