tests/qtest/migration: Remove vmstate-static-checker test

I fumbled one of my last pull requests when fixing in-tree an issue
with commit 87d67fadb9 ("monitor: Stop removing non-duplicated
fds"). Basically mixed-up my `git add -p` and `git checkout -p` and
committed a piece of test infra that has not been reviewed yet.

This has not caused any bad symptoms because the test is not enabled
by default anywhere: make check doesn't use two qemu binaries and the
CI doesn't have PYTHON set for the compat tests. Besides, the test
works fine anyway, it would not break anything.

Remove this because it was never intended to be merged.
