Android: Remove gradle.properties file handling

The modification of gradle.properties files was originally a feature of
the Android plugin which eventually moved over to androiddeployqt.

Moreover, this code got accidentally disabled in Qt Creator 4.10 and was
appartently not missed till now. I only noticed it while "FilePath-
ifying" code in the Andsroid plugin.

This change removes the gradle.properties file handling code from Qt
Creator.

Fixes: QTCREATORBUG-28494
