sys/linux: support CO-RE info in PROG_LOAD command
Commit [1] upstream added support via the bpf(2) PROG_LOAD command to
load BTF CO-RE relocation data. This commit adds basic support for
loading the same data in syzkaller. As usual with BTF, we are pretty
limited in what we can efficiently describe :-(
