Fix main() not being visible on Android

Browse Source 
A recent change refactored the call to qt_internal_add_executable(),
but that had the unintended side-effect of changing the symbol
visibility from public to hidden. That meant that main() became hidden,
so while apps still built successfully, they could not be run. Restore
the original symbol visibility to fix this regression.
