Jiayuan Chen cfce77b633 bpftool: Skip prog/map that disappears while looking it up by name ...

Looking up a prog or map by name walks the whole id space. There is a
window between bpf_prog_get_next_id()/bpf_map_get_next_id() and getting
an fd for that id in which an unrelated object can be freed, and the
lookup then fails with ENOENT and aborts the whole command.

Skip such ids and keep walking, the same way do_show() already does.
