Fix detection of the proxy base style when QT_STYLE_OVERRIDE is set

Browse Source 
QProxyStyle checks QApplicationPrivate::styleOverride but ignores
QT_STYLE_OVERRIDE when it is trying to detect the name of the base
style.
Set styleOverride from QT_STYLE_OVERRIDE to make it work. Thus there
is no need to check QT_STYLE_OVERRIDE from multiple places.
