[ci skip] Update README

ant 1.9.0 breaks RubySpec runs (https://gist.github.com/BanzaiMan/5307126)
Reorganize Travis build configuration to ruby RubySpec

Travis will run 3 jobs:

RubySpec runs are at the moment allowed to fail, but we will (surely!)
fix them shortly.
Upgrade to jffi-1.2.7 for issue #626
Update to jnr-ffi-1.0.4, (also version bump jnr-enxio-0.4, jnr-netdb-1.1.2, jnr-posix-2.5.2, jnr-unixsocket-0.3)
Use DottedFormatter, so that Travis doesn't kill spec runs due to lack of output
