podman machine: do not commit proxies into config file

qemu fails when the same `fw_cfg` options is used more than once.
Since the current logic always adds a new option on each machine load
this will fail on the second start.

We can fix this by checking if the option is already set and replace but
I think it is easier to just not commit the option in the config and add
it dynamically on start. User that hit this bug have to recreate the
machine.

[NO NEW TESTS NEEDED]

Fixes #14636
Fixes #14837
