Move pointer the correct direction when trying to skip spaces

gpsd_set_century attempts to skip optional whitespace in its input, but
it does so by decrementing its pointer, when it should instead be
incrementing it.

Eric, I feel this one should make the snap release. It's trivial,
isolated from other code, and I hope is "obviously correct".

I have further patches in my queue, which I'm sending shortly, but which
I don't think should necessarily go in the current snap release. None of
them is critical.
