Subject: qtbase: Reorder EGL libraries from pkgconfig and defaults:

https://bugreports.qt.io/browse/QTBUG-50838
https://bugreports.qt.io/browse/QTBUG-52739

The modification is the less intrusive possible. It only swaps LIBS and QMAKE_LIBS_EGL.
The reason behind that was that for the RaspberryPi:
 *  -lEGL -GLESv2 can link
 *  -lGLESv2 -lEGL can't

Adding -lEGL -lGLESv2 and then -lEGL gives -lGLESv2 -lEGL ... the libraries swaped.
