backends/native: update glyph cache on resume

Browse Source 
As mentioned in a previous commit, the proprietary NVIDIA
driver garbles memory on suspend. That behavior, means that
clutter's glyph cache (which is stored in GPU memory) gets
corrupted on suspend.

This commit ensures the glyph cache is blown away when
the logind session becomes active (on VT switch and resume).
