Subject: [PATCH 1/2] Allow running benchmarks on pull requests

The custom dockerfile allows installing system dependencies like zlib,
the Makefile has the "make bench" target that is run once all the
dependencies are installed and the opam file allows installing necessary
dependencies for the benchmarks.
