bpf: Re-support uid and gid when mounting bpffs
For a clean, conflict-free revert of the token-related patches in commit
d17aff807f84 ("Revert BPF token-related functionality"), the bpf fs commit
750e785796bb ("bpf: Support uid and gid when mounting bpffs") was undone
temporarily as well.
This patch manually re-adds the functionality from the original one back
in 750e785796bb, no other functional changes intended.
Testing:
# mount -t bpf -o uid=65534,gid=65534 bpffs ./foo
# ls -la . | grep foo
drwxrwxrwt 2 nobody nogroup 0 Dec 20 13:16 foo
# mount -t bpf
bpffs on /root/foo type bpf (rw,relatime,uid=65534,gid=65534)
Also, passing invalid arguments for uid/gid are properly rejected as expected.
Fixes: d17aff807f84 ("Revert BPF token-related functionality")
