commit 4680a93d516f5b61d5c865378c3a43e9ba9b0598
Author: Bastien Nocera <hadess hadess net>

tests: Add GMemoryMonitor installed-tests
Those tests require Python, gobject-introspection and python-dbusmock
making them unsuitable to be run within the uninstalled test suite.
There are no restrictions of dependencies when it comes to installed
tests so use those to exercise GMemoryMonitor.
