ansible-test - Update locale logic to match core. (#78389)

Now that core requires UTF-8 filesystem encoding, ansible-test does as well.

Additionally, the `en_US.UTF-8` or `C.UTF-8` encoding must be available.
Previously the `en_US.UTF-8` encoding was requested, but its availability was never verified.
The fallback to `C.UTF-8` maintains UTF-8 encoding while allowing more flexibility in the running environment.
