[PATCH master] Makefile: pass KBUILD_OUTPUT to pytest in check target

[Ahmad Fatoum]

The check target runs pytest from the source directory, but doesn't
propagate the build output directory. conftest.py falls back to
using build/ if it exists, which may contain a completely different
configuration.
