gitpkgv: Fix $GITPKV for a single named git source

Recipes that fetch from a single git source, assign a name to this
source and do not set SRCREV_FORMAT to this name will always get
a GITPKGV value of "default", which causes version-going-backwards QA
errors.

Fix this by automatically determining a suitable SRCREV_FORMAT from the
SRC_URI if none is set explicitly. This code does not run for multiple
git sources, because bitbake's fetcher enforces setting SRCREV_FORMAT
when multiple version-controlled sources are used.
