CMake: Fix location of iOS framework prl files

Browse Source 
iOS prl files for static frameworks were previously placed at a path
like
  6.8.3/ios/lib/QtCore.framework/Versions/A/Resources/QtCore.prl

This caused qmake to silently fail to find iOS framework prl files.
The failure could only be seen when calling qmake with -d -d:

  DEBUG 2: QMakeMetaInfo: Cannot find info file for
    6.8.3/ios/lib/QtCore.framework/Resources/QtCore.prl

This in turn can lead to various build failures if a different non-iOS
prl file is found in a system path.

Place the prl file into the root of each framework, e.g. at
  6.8.3/ios/lib/QtCore.framework/QtCore.prl

We didn't have this issue in 6.7 and earlier, because by default iOS
was built with static libraries rather than static frameworks.
