qt4-imx-support: fix build for imxgpu2d SOCs

Before this change, when imxgpu2d is selected, the qt4 do_configure
fails with the following error:

| EGL (EGL/egl.h) auto-detection... ()
| compiling egl.cpp
...

| The EGL functionality test failed!

This is because the -DLINUX=1 and -DEGL_API_FB=1 flags added to QT_CONFIG_FLAGS
are not pushed down during these configuration tests.

This commit adds these two flags directly to the related .pro files
in Qt4 sources.

Since it's been a long time that meta-qt4 is not updated anymore,
the patch can be backported to LTS releases.
