Daniel Borkmann 0901df3aea bpf: use prefix_len in test_tag when reading fdinfo
We currently used len instead of prefix_len for the strncmp() in
fdinfo on the prog_tag. It still worked as we matched on the correct
output line also with first 8 instead of 10 chars, but lets fix it
properly to use the intended length.
