Patch to add bpf-related directories

Description of problem:

The kernel eBPF subsystem allows applications to load bytecode into the kernel for various purposes. Not many applications are including such bytecode yet, and so we want to establish a convention for where to store bytecode files to encourage applications to be consistent in this, and make it easier to identify which packages are the source of eBPF programs running on the system.

To this end, the attached patch adds the following directories to the 'filesystem' package:

For pre-compiled eBPF bytecode files:
/usr/%{_lib}/bpf
/usr/local/%{_lib}/bpf

For caching runtime-generated eBPF bytecode:
/var/cache/bpf
