Remove unused CMake helper files

These files are not used anywhere. The only remaining cmake find files
are:

- findarmral and findxran: used by FHI7.2 driver
- findsctp: used by top-level CMakeLists.txt
- findgnutls: NOT actually used but GnuTLS is a dependency of websrv, so
  I leave it for the moment (should be removed if the webserver is
  removed)
