.gitignore update

Somehow I ended up with the following in tree:

	$ git status
		...
	# Untracked files:
	#   (use "git add <file>..." to include in what will be committed)
	#
	#       fs/proc/root.o.FuMxJQ
	#       net/ipv4/tcp_minisocks.o.geCDYR

These are presumably temporary gcc files, which aren't interesting.
