tools: bpftool: use more common tag format
Program tag is usually displayed as string of bytes without
any separators (e.g. as "aa5520b1090cfeb6" vs MAC addr-like
format bpftool uses currently: "aa:55:20:b1:09:0c:fe:b6").
Make bptfool use the more common format both for displaying
the tag and selecting the program by tag.
This was pointed out in review but I misunderstood the comment.
