linux/mac: use "First Run", not "First Run Dev"
linux/mac: use "First Run", not "First Run Dev"

This should've been done back when we finished the First Run dialogs,
but better late than never.

BUG=24397
TEST=Run Chrome on an old profile; you should not get a first run dialog if you've already clicked through and your user data dir should now contain a "First Run" file and no "First Run Dev" file.  Run Chrome on a new profile; First Run should still work as before.
