sci-libs/xdmf2: Remove heuristics to help detect HDF5_ROOT

Gentoo-bug: 591302
* EAPI=6
* Add missing RDEPEND on dev-libs/boost
* Add ${PYTHON_REQUIRED_USE} to REQUIRED_USE
* [QA] Byte-compile XdmfCore.py and Xdmf.py
* Thanks to Michael Palimaka <kensington@gentoo.org> for
  helping to identify the culprit

Package-Manager: portage-2.3.0
