bash_completion: Fix cros autocompletion
Currently user would get '/bin/grep: Invalid range end' when trying to
autocomplete after 'cros '. This is because the '-' in the regex is
interpreted as range. Fix this by moving the - to the end of character
group.
BUG=None
TEST=manually try autocomplete 'cros '
