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.
