Fix fates paramgen in tests

[mvdebolskiy]

Description of changes

Removes FatesSetupParamBuild from some fates tests that need to have fates_paramfile changes. Since we do not need to use ncgen anymore. Also change $SRCROOT in those tests to COMP_ROOT_DIR_LND to be able to run these tests in the coupled model checkout (or in CISM-standalone f.e., or in CAM-standalone).

@mvdebolskiy Would you mind bringing this up-to-date with ctsm5.4.041 before I review? It looks like there are a couple of conflicts you'll need to resolve. Thanks!

[mvdebolskiy]

@samsrabin resolved.

Looks good! Did you need one of us to do the testing?

[mvdebolskiy]

@samsrabin I can run the tests which this PR touches, If you give me the --baseline-root on derecho. But probably tomorrow. I've tested it before by running the nprt2 testmod and TwoStream on betzy and also doing namelist only on aux_clm on derecho.
