apps: qcam: Disable -Wsfinae-incomplete

Browse Source 
GCC-16 has updated the warnings enabled and now includes
-Wsfinae-incomplete triggering breakage in the included headers from
Qt6:

/usr/include/qt6/QtCore/qregularexpression.h:31:21: error: defining ‘QRegularExpression’, which previously failed to be complete in a SFINAE context [-Werror=sfinae-incomplete=]

This is a Qt header issue outside of libcamera’s control. Disable the
warning for qcam to restore buildability with newer GCC versions.
