Fix undefined machine on cime6.0.217_httpsbranch branch

[ekluzek]

Initialize machine to None to prevent not initializing it to anything. This is cherry-picked
from #4596

Testing: Run CTSM python testing (which was failing before this change)
./scripts_regression_tests.py (currently running)
Test status: bit-for-bit

Fix for #4588 on the httpsbranch branch.

This fixes issues in CTSM discussed here:

ESCOMP/CTSM#2385 (comment)

User interface changes?: None

Update gh-pages html (Y/N)?: N

If this could be merged and then tagged as cime6.0.217_httpsbranch03 that would be great.

Thanks for porting this over to this branch.

I ran the scripts regression testing script for an hour (until it ran out of wallclock). I could give it more time and restart. But, for this I think it's probably sufficient.

Here's the output to show how far it got...

Warning: no access to tty (Inappropriate ioctl for device).
Thus no job control in this shell.
