guix/gnu/packages/patches/upower-builddir.patch

Remove explicit set of UPOWER_CONF_FILE_NAME in up-self-test.c;
instead the harness should set it.  In Guix we set it explicitly; the
right thing is to use AM_TEST_ENVIRONMENT and regenerate the
makefiles, but we can't regenerate because current autotools carp on
some things, so we patch the Makefile.in instead.

Also fix to not try to create /var/lib/upower if /var isn't writable.
