Build the extcap programs in the extcap directory.
That lets the version of Wireshark built with autotools find the extcap programs. Don't install the extcap programs under ${datadir} - that puts it under a share directory, and share directories are for platform-independent files, which executable images aren't (they're instruction-set dependent, hence platform-dependent).
