Fix Unexpected crash_sender stdout/stderr when testing Official image

logging_KernelCrashServer and logging_UserCrash tests fail on an Official
image, because crash_sender's is_official() test leaks the "Official" line:
grep needs the quiet option (and does not need a cut).

BUG=837
TEST=logging_UserCrash
