Fix grep commands in init scripts.
The exit status of a pipeline is the exit status of the last command in
the pipeline. If the last command is ":", the exit status will always
be 0, regardless of whether grep finds the specified pattern.
So just use grep's -q command. According to the documentation for GNU
grep, some older grep implementations lacked this option. But we're
only running these scripts on BusyBox grep, which unconditionally
includes this option.
