Gonéri Le Bouder a3407682ed ansible-test: fix the vcenter+vcsim support
The vcenter provider allow one to use the `VMWARE_TEST_PLATFORM` to
manually select a test platform. The test platforms are:

- `govcsim`
- `static`
- and `worldstream`.

Before this commit, the `govcsim` value was ignored.

Example:

```shell
$ VMWARE_TEST_PLATFORM=govcsim ansible-test integration --python 3.7 needs/target/prepare_vmware_tests/
```
