tests: extract _test_virtio_block_topology wrapper

Browse Source 
Extract test logic from test_virtio_block_topology into
a shared _test_virtio_block_topology wrapper function in
tests_wrappers.rs. The loop device creation and cleanup
are kept in the parent test case. The wrapper uses
default_kernel_cmdline() for kernel/cmdline setup.
