One change: turns out that zeek-config isn't in PATH, so I prefixed it
with $BUILD.

zeek-setup: Validate plugin debug streams during startup
Providing an unknown plugin debug stream with -B was previously silently
accepted. This caused user confusing as the behavior is "no output, but
seems to work".
Check the enabled debug streams once all plugins have been loaded and
exit early on for invalid streams.
$ ZEEK_PLUGIN_PATH=./build zeek -B plugin-zeek-myplugin -e 'print zeek_version();'
error in <command line>, line 3: No plugin debug stream 'plugin-zeek-myplugin' found
Closes#913.
