Add a test for using xdp_md as a context to BPF_PROG_TEST_RUN for XDP programs. The test uses a BPF program that takes in a return value from XDP meta data, then reduces the size of the XDP meta data by 4 bytes. Test cases validate the possible failure cases for passing in invalid xdp_md contexts, that the return value is successfully passed in, and that the adjusted meta data is successfully copied out.
