qtbase: install and split package fonts

- fonts were not installed (at least in qt 5.0.2) so install
them manually.
- split the font package in smaller package as done in qt4 to
save space on the target.
- use OE_QMAKE_PATH_LIBS which corresponds with:
  mkspecs/features/qpa/genericunixfontdatabase.prf:    fonts.path = $$[QT_INSTALL_LIBS]/fonts
