[PATCH v3 1/3] patchtest: use HEAD commit as base for the selftest and not master

[Alexander Kanavin <alex.kanavin@gmail.com>]

From: Alexander Kanavin <alex@linutronix.de>

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:
https://valkyrie.yoctoproject.org/#/builders/71/builds/460
