[ Upstream commit ad93ba02678eda5fc8e259cf4b52997e6fa570cf ]
Currently selftests require xxd with the "-n <name>" option which allows the user to specify a name not derived from the input object path. Instead of relying on this newer feature, older xxd can be used if we link our desired name ("test_progs_verification_cert") to the input object.
Many distros ship xxd in vim-common package and do not have the latest xxd with -n support.
