Support old plugins that use files within the source/build tree

Browse source 
Plugins that were made using an older skeleton (e.g. from Bro 2.5.x)
may still reference "bro-config.h", "bro-path-dev", or "bro" from the
build tree, so we can simply provide compatibility symlinks/wrappers
for the new files that use "zeek" in their names.
