buildah bud tests under podman-remote

New functionality -- mostly in the diffs we apply to
buildah's helpers.bash -- to enable running buildah-bud
tests under podman-remote. The gist of it is, we start
a 'podman system service' before each test, and clean
it up on test exit.

Design decision: the diff file for helpers.bash is no
longer trailing-whitespace-clean: that ended up producing
diffs that git wouldn't apply, because in some cases
the whitespace is actually important. In order to pass CI,
we need to exclude this file from some checks.
