backend-drm: remove unecessary ifdef checks

Browse Source 
Since commit 28d26483 ("build: bump libdrm requirement to newer version
(2.4.83)"), all supported libdrm versions provide modifier formats,
atomic API and blob formats. Remove ifdef checks (HAVE_DRM_ADDFB2_MODIFIERS,
HAVE_DRM_ATOMIC, HAVE_DRM_FORMATS_BLOB) to improve the code and make it
simpler.
