orog.fd - Reduce dependency on SPLIB and some cleanup (#889)

- Remove routines MAKEMT, MAKEPC and MAKEOA, which were used for the old spectral GFS 
gaussian grid (and have dependencies on SPLIB) and are now obsolete.
- Remove write of the GRIB1 version of the 'orog' file. That was only used for the old spectral 
GFS and had dependencies on SPLIB.
- Remove write of old binary version of the 'orog' file, which was used for the old spectral GFS.
- Remove BACIO library from the build.
- Remove unused variables and perform some general cleanup.

Fixes #886.
