Some versions of SLES apparently don't define the _sharedstatedir RPM
macro properly, leaving it at the old-time UNIX /usr/com default. This
was causing the server to fail to start on such platforms because the
expected data directory at /var/lib/mongodb was missing. The macro is
now statically defined on SLES to /var like it should be on any modern
Linux distribution.
Also fixed were paths to systemd unit files in package testing and the
fact that we weren't installing the tools-extra package, which we should
be doing if only to verify that the script indeed continues to fail
expectedly on the platform.
