Assume FreeBSD hosts include support for fetching signal information.

The current layout of siginfo_t and support for fetching it has been
included in FreeBSD kernels since 7.0 release.  The most recent
release without support is 6.4 released in November of 2008.

gdb/ChangeLog:

	* fbsd-nat.c: Always include support for
	TARGET_OBJECT_SIGNAL_INFO.
