Added '--skip-preview-namelist' to case.build

Added '--skip-preview-namelist' to case.build. This will allow the user
to specify if the namelist should be rebuilt from user_nl_8.

In this particular commit I added '--skip-preview-namelist' to the call
for case.build in the testing suite, since building namelists during
tests isn't done.

Test suite: scripts_regression_tests.py
Test baseline:
Test namelist changes:
Test status: bit for bit

Fixes #1276, E3SM-Project/E3SM#1466 (comment)

User interface changes?: Added --skip-preview-namelist to case.build and
template.case.run

Code review: @jgfouca, @rljacob
