sys/linux: support for loopkup-free map value accesses
A new BPF instruction that allows lookup-free map value accesses was added
in Linux v5.2, with commit d8eca5b ("bpf: implement lookup-free direct
value access for maps"). It enables direct access to map values without
having to call a BPF helper. It is currently used to implement global
variable support.
This commit adds support for that new instruction.
