Fix symbol exports in QtScript with gcc

Symbols declared as extern "C" will always be exported even when using
-fvisibility=hidden (see gcc man-page).

Instead of exporting we surround the extern declaration with a pragma
push and pop to change the default visibility.

In addition the use of HIDE_SYMBOL was missing in the "arm traditional"
branch for declaring the trampoline functions in JITStubs.cpp
