Reverts broken portion of old character pushback change.

This one instance of the 63 character-pushback changes in commit
fbaaaa76 broke the packet-regress test, though that was masked due to
another bug's causing that test to be disabled.  With this instance
reverted, the test passes again.

It's not entirely clear why a change within Zodiac-specific code broke
one SiRF test and two Evermore tests, but that's empirically the case.

This change affects one daemon regression test.  The ublox-8 test
begins with a $GPRMC sentence preceded by a bunch of garbage.  The
broken version of packet.c skips this sentence, while the fixed
version recognizes it.  The test data has been updated accordingly.

TESTED:
Manually ran the packet-regress test successfully.
Ran "scons build-all www check".
