Modified files:
	usr.bin/vi/build: recover 

Log message:
Remove the races so that this is safe to run anytime.  We open
/var/tmp/vi.recover to get an fd and user O_NOFOLLOW to following a symlink.
Once we have a file handle we can use it to safely chdir to the right
place and form then on do operations relative to ".".  Also restrict
to root.
