[PATCH v3] security: selinux: allow per-file labeling for bpffs

[Steven Moreland]

From: Connor O'Brien <connoro@xxxxxxxxxx>

Add support for genfscon per-file labeling of bpffs files. This allows
for separate permissions for different pinned bpf objects, which may
be completely unrelated to each other.
