patchtest: use HEAD commit as base for the selftest and not master

Patchtest applies patches on top of poky master branch by default;
this means selftest does the same, and any commits from the branch-under-test
are then discarded.

This can cause issues for example, if bitbake-server process started by selftest
from the master branch tries to parse bitbake.conf from the branch under test:
