list_ncvars.csh set alias to list_ncvars (the Fortran program)

[underwoo]

Describe the bug
Looking at the list_ncvars.csh, the script sets an ailas of list_ncvars to list_ncvars.exe. The .exe is no longer set for non-windows installations. While it appears the script is working, this should be removed.

Note, it may be worth rewriting this script in a POSIX shell, or another interpreted language (e.g, python) at the same time.
