Add install tests `tearDown()` support for Suse OS family.
Allow errno 4 exit codes from zypper to be ignored.
Skip install test if there's no `tearDown()` support.
Suse packages needs some help to properly un-install.
Suse packages provide `salt-syndic` as a separate package.
Add `salt-syndic` to the tearDown packages.
Packages are now properly cleaned up for Suse distro's on install tests.
Allow running `install-testsuite-deps.py` reducing the needed imports, specially, `unittest2`.
Fix imports in `runtests.py`.
Properly detect and handle SLES SP2 on `install-testsuite-deps.py`.
Add support for SuSE 11, at least SP2, but SP1 should also work. Refs #56.
1:1 mapping from openSUSE to SLES regaring the `tearDown()` functions.
Force `python-M2Crypto>=0.21` because SLES also has `0.19` and there's no automatic way to choose which gets installed.
Handle services setup/start/stop for SuSE which does not have `systemctl`. Refs #56.
SuSE git installations should be installed with `--prefix=/usr` not `--prefix=/usr/local`.
