Don't return stale data from fbsd_pid_to_exec_file for kernel processes.
For processes without an associated executable (such as kernel processes),
the kern.proc.pathname.<pid> system control node returns a length of zero
without modifying the user's buffer. Detect this case and return NULL
rather than the previous contents of the static buffer 'buf'.
gdb/ChangeLog:
* fbsd-nat.c (fbsd_pid_to_exec_file) [KERN_PROC_PATHNAME]: Return
NULL for an empty pathname.
