EX-4015 lipe: add lipe-scan RPM

Adding new dependencies to existing EXAScaler RPMs may create
headaches when distributing hotfixes to existing installs. So move
lipe_find3 and lipe_scan3 to a new RPM (lipe-scan). This also has the
benefit of explicitly severing the new scanning tools from any python2
RPM or pip dependencies.

Compile fid.scm and find.scm to (%site-ccache-dir)/lipe/.
