Subject: bpftool: bpf_link_get_from_fd support for LSM programs in lskel
Patch-mainline: v5.19-rc1
Git-commit: bd2331b3757f5b2ab4aafc591b55fa2a592abf7c
References: jsc#PED-1377

bpf_link_get_from_fd currently returns a NULL fd for LSM programs.
LSM programs are similar to tracing programs and can also use
skel_raw_tracepoint_open.
