Update n4zip to fix deprecated option

[mathomp4]

As pointed out by @gmao-yzhu, when you run n4zip you get a big warning from NCO:

> /discover/nobackup/mathomp4/SystemTests/builds/AGCM/CURRENT/GEOSgcm/install-Release/bin/n4zip stock-2024Jul26-1day-c24-SLES15.geosgcm_prog.20000415_1800z.nc4
/discover/nobackup/mathomp4/SystemTests/builds/AGCM/CURRENT/GEOSgcm/install-Release/bin/n4zip: working on stock-2024Jul26-1day-c24-SLES15.geosgcm_prog.20000415_1800z.nc4  ...ncks: WARNING the ncks '-a', '--abc', and '--alphabetize' switches are misleadingly named because they turn-off the default alphabetization. These switches are deprecated as of NCO 4.7.1 and will soon be deleted. Instead, please use the new long options --no_abc, --no-abc, --no_alphabetize, or --no-alphabetize, all of which turn-off the default alphabetization.
 ok

So, to avoid this, we update the --abc to --no-alphabetize.

Also, add -f to the csh shebang. Always good practice.
