ZISFGUX is not necessary

[Jon Tai]

Our first alpha release added a routine, ZISFGUX. It also modified ZTMGRSET to copy ZISFGUX as %ZISF on GT.M/Unix systems.

Upon further inspection, this is probably not necessary, since ZISFGUX only differs from ZISFGTM in trivial ways:

We should revert the change to ZTMGRSET and delete ZISFGUX.
