We need it again after the upgrade to Lucene 5.4.1.
This reverts commit 08cc835f99961b19b41c5958f5bdafe7ee458cc4.

Since I146fc74ed6 core-and-backward-codecs target was removed but
the toolchain that was added to merge non-generically maven JARs
was preserved. Remove it as well. We hope that we don't need it
and if yes, it would be easy to restore it again.

Both of these jars provide a provider-configuration file in
META-INF/services/org.apache.lucene.codecs.Codec registering their
respective implementations as providers of this codec. The proper way
to merge these files is to concatenate them, but the normal Buck build
process would otherwise choose one arbitrarily.
Add a new custom rule merge_maven_jars to merge multiple Maven jars
together using a simple Python script. The script concatenates all the
entries in two zip files, preferring the entry found in the first file
on the command line, which is still arbitrary but at least
deterministic. It specially handles files in the META-INF/services
directory by concatenating them.
Use this new rule to merge the old :core and :backward-codecs rules
into a single :core-and-backward-codecs rule.
