selftests/bpf: Allow selftests to build with older xxd
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.
Fixes: b720903e2b14d ("selftests/bpf: Enable signature verification for some lskel tests")
