Mykyta Yatsenko a73f1ba994 bpf: Return prog btf_id without capable check ...

[ Upstream commit 07651ccda9ff10a8ca427670cdd06ce2c8e4269c ]

Return prog's btf_id from bpf_prog_get_info_by_fd regardless of capable
check. This patch enables scenario, when freplace program, running
from user namespace, requires to query target prog's btf.
