sci-geosciences/qgis: Bump to v2.14.5

 - Version bump to new upstream release v2.14.5 (Fixes Gentoo-Bug #581146,
   #583784, #588994).

 - Bumped to EAPI=6; This makes multilib eclass unnecessary because
   get_libdir is now part of EAPI=6.

 - "oracle" USE flag added (Fixes Gentoo-Bug #585156).

 - Disabling test suite because upstream doesn't allow running from
   install path [Link 1] (Closes Gentoo-Bug #499894).

 - Package license updated after upstream clearified its own license
   [Link 2].
