LU-3953 rpm: stop using unnecessary file lists

File lists are being generated for unconditonally packaged files.

RPM can handle both static and dynamic file lists, so let's use them.
It simplifies the spec file quite a bit.

There are also some files that are treated as being conditionally
included but the conditions are always true:

- lustre_types.h was removed in commit adde80ff (v1.9.50)
- libcfsutil.a was made unconditional in commit b279ac68 (v2.3.51)
- include/lustre/lustre_idl.h was added in commit 11330397 (v1.7.100)

I've removed the conditionals surrounding these and moved them into
the static file lists.
