pkg/machine: make checkExclusiveActiveVM race free
We need to take another lock to prevent concurrent starts from different
machines.

I manually tested it by starting three VM in parallel with:
podman machine start & podman machine start test1 & podman machine start test2

I also added a CI test that seems to work as expected (failed with the
old binary, worked with the new)

Before this patch I was able to start more than VM, with this patch it
now only starts one of them and the other ones will fail to start with
a proper error.
