sys/linux: make bpf_lsm_btf_id optional (#2054)

Browse Source 
Pull request #1971 add the resource bpf_lsm_btf_id and make that a
required resource for bpf$BPF_LSM_PROG_LOAD. However, we need #2035
merged to get a bpf_lsm_btf_id, and the pull request is currently
blocked by a pahole issue. Thus, bpf$BPF_LSM_PROG_LOAD will be disabled
for now.

This pull request makes bpf_lsm_btf_id optional for
bpf$BPF_LSM_PROG_LOAD, so we can test this syscall before the issue is
resolved.
