Bug: http://b/328180685
Test: m libdrm_fourcc
Test: atest drm-fourcc_test_src_lib

Note: the latest version on crates.io does *not* contain the LICENSE
file, even though it's marked as MIT-licensed in Cargo.toml. The main
branch on github [1] has the LICENSE file (which I included here).
Please let me know if that's OK.
