[Ubuntu] Hardcoded GDAL version in QGIS package

[Johan Van de Wauw]

I have no access to a trusty box now, but as a quick solution, try
reverting the update of gdal: sudo apt-get install libgdal1h=gdal -
1.11.1+dfsg-1~exp2~trusty


Bas: trouble is that with grass7 in ubuntugis qgis is now refusing to
build. Should be easy to fix - but it is more work than just bumping
the version number (which I tried first).
I'll try tonight if I can fix it.
