pmtest: set LC_ALL=C in subprocess.call

LC_ALL=C is required to force pacman's output to English for tests that
rely on that output, but setting it in Makefile.am results in those
tests breaking under different locales when pactest.py is run directly.
This will also ease an eventual transition to python3 which LC_ALL=C
causes to default to ascii encoded strings, creating problems for tests
with unicode strings.
