tests: add lvm_vdo_wrapper
Introduce a replacement vdo manager wrapper for testing. When using test suite on a system without vdo manager (which has got deprecated) - we still need its functionality to prepare 'vdo volume' for testing lvm_import_vdo. Wrapper currently need 2 binaries from older 'vdo 6.2' package - to be named: oldvdoformat - format VDO metadata with older format oldvdoprepareforlvm - shift vdo metadata by 1MiB
