Tvrtko Ursulin 1ea96af776 gem_ppgtt: Test VMA leak on context destruction
Test that VMAs associated with a context are cleaned up when
contexts are destroyed.

In practice this emulates the leak seen between fbcon and X server.
Every time the X server exits we gain one VMA on the fbcon frame
buffer object as externally visible via for example
/sys/kernel/debug/dri/0/i915_gem_gtt.

v2: Use igt_debugfs_open, getline and strstr instead of home-brewed
string matching. (Thomas Wood)

v3: Rebase for drm_open_driver.
