libdrm: update to version 2.4.120
Prerequisites for Mesa 24.0.1
* generic:
* add patch to retrieve PCI/Platform information from Genode side of the DRM
interface (in drmGetDevice2)
* add generated 'fourcc' file
* iris:
* report back-end (currently 'i915', 'xe' is unsupported)
* add various I915_CONTEXT_PARAM* and I915_PARAM*
* allocate 'Buffer's starting with ID 1 (0 is invalid)
* enforce 48-bit-address limit on unmap also
* disable I915_EXEC_FENCE_ARRAY array check, because we do not support
sync objects right now and rendering in synchronous
* etnaviv:
* create 'Fenceobj' only *once* for each GPU context
issue #5224
