dracut-module-setup: Fix DRM module inclusion test for hyper-v

Browse Source 
We test if to include the drm module or not by testing if there are any
drm entry in sysfs. But there is an exception for hyper-v, DRM module
take care of hyperv's framebuffer driver as well but hyperv_fb will
not create any drm entry. So currently we got black screen on
hyperv guest.

Fix by detect hyperv's special entry as well.
