add/list: reinstate a default bpf directories list
Currently, each install of udev-hid-bpf
is hiding any other installation
path for finding their bpf object files.
This is problematic when we need users to test a branch, because this way
we hide any system-wide installation of udev-hid-bpf
and any bpf object
files shipped with it.
Let's remove the statically generated directory list and hard-code the most sensible ones.
This way, a manual reinstallation should still be able to reach the system-wide installation while keeping the new files around.
Closes #20 (closed)
