Fix Bug 9951: 'git commit hook isn't calling checkAPIs.pl with arguments for the dissectors'

I recently made a change to packet-rtp.c and inappropriately included
g_error() in it, which the builbots caught during their run of checkAPIs.pl.
But checkAPIs.pl is supposed to catch such things for us before we submit, by
being invoked in the git pre-commit hook.

Apparently though, buildbots call checkAPIs.pl with extra arguments for
different cases... and for packet dissectors it calls it with a '-g abort'
argument, which is how it caught the g_error.

So the "bug" is that the pre-commit hook should invoke checAPIs.pl with that
argument too, for epan/dissectors/packet-*.c files.
