CMake: Write gcc sysroot flags to qconfig.pri

Browse Source 
For a cross-built, gcc-built Qt, the qmake build writes code into
qconfig.pri that adds the --sysroot flag to compiler and linker flags.
Follow suit in the CMake build.

To keep the diff small between the qmake-generated and CMake-generated
qconfig.pri files, the sysroot code is added at the top of
qconfig.pri, which is the reason for the new 'content' string variable.
