Remove unmaintained modulefiles

[DusanJovic-NOAA]

The following 3 modulefiles seem to be unmaintained for quite some time:

• ufs_expanse.intel last update 3 years ago
• ufs_odin last update 3 years ago
• ufs_stampede.lua last update last year

They should be removed from the repository. Or updated to load the current version of the libraries model depends on, if anyone is still using them.
