LU-6001 build: cleanup build scripts after reorganization

After passing a few configuration parameters in "--with/--without"
option to rpmbuild some code become useless.

Don't pass options through configure_args that can be passed through
rpmbuild options. This allows to avoid unexpected behavior during
the build from source rpm.

Change module-dist-hook: target according coding guidelines.

Remove obsolete liblustre.{a,so} from .spec file that were actually
removed in commit cdfbc722f4d63d3ed3740cbb549062f712010d90.

Don't add the version of kernel to .src.rpm.
