sima0_09_001: Update CAM7 gravity waves snapshot (#458)

Tag name (required for release branches): sima0_09_001
Originator(s): @jimmielin 

Description (include the issue title, and the keyword ['closes',
'fixes', 'resolves'] followed by the issue number):
- Fix #457 by updating with CAM7 snapshot made with cam6_4_141
- Update to atmos_phys atmos_phys0_20_000 to bring in latest tag in sync
with CAM

Describe any changes made to build system: N/A

Describe any changes made to the namelist: N/A

List any changes to the defaults for the input datasets (e.g. boundary
datasets):
- Updated snapshot file for cam7 GW

List all files eliminated and why: N/A

List all files added and what they do: N/A

List all existing files that have been modified, and describe the
changes:
(Helpful git command: `git diff --name-status
development...<your_branch_name>`)
```
M       .gitmodules
M       src/physics/ncar_ccpp
  - bring in atmos_phys0_20_000

M       cime_config/testdefs/testmods_dirs/cam/outfrq_gw_cam7_derecho/user_nl_cam
  - update snapshot for CAM7 GW
```

If there are new failures (compared to the
`test/existing-test-failures.txt` file),
have them OK'd by the gatekeeper, note them here, and add them to the
file.
If there are baseline differences, include the test and the reason for
the
diff. What is the nature of the change? Roundoff?

If this changes climate describe any run(s) done to evaluate the new
climate in enough detail that it(they) could be reproduced:
