[PATCH]: gnu: Add RSeQC.

[Ricardo Wurmus]

Attached is a patch to add RSeQC to the bioinformatics module.  It only
works with Python 2.7.  I removed the bundled copy of pysam to be able
to use our python-pysam package instead.

The license isn't very clear.  The Google Code website[1] lists the
license as "GPLv3", but nowhere in the source is the license version
specified.  "PKG-INFO" declares "License :: GPL", whereas
"./doc/COPYING" contains the MIT license.  It's all pretty messy, so I
contacted one of the authors to ask for clarification.

Apart from the license issues (which need to be solved before adding
RSeQC), does this patch look okay?
