While --extcap-interfaces is now run in parallel, --extcap-config (for
each discovered interface) would only run sequentially after that. Make
sure that the latter command also fully parallel and do not wait for all
extcap interfaces to be discovered first.
This saves another 80ms startup time on Linux (unoptimized ASAN+Debug).

Split interface discovery in three stages: discover available programs
(extcap_get_extcap_paths), obtain outputs for each (extcap_run_all) and
processing of the output (process_new_extcap). The second step is most
expensive, do it in parallel in multiple threads.
extcap_foreach used to call extcap_if_exists, but as "cb_info.ifname" is
always NULL for interface discovery, it would always pass. Remove this
check and all other unused functions.
This saves 100ms startup time on Linux with 7 extcap tools.

extcap_foreach has two purposes: discovery of all interfaces for each
tool and querying info for an extcap interface. Observe that the latter
requires extcap_if_exists(ifname) to be true. This makes extcap_foreach
match exactly one interface, so we can avoid some complexity.

Name choice mimics those used by tcpdump(1), which already supports this
