[RFC PATCH 4/4] ui/cocoa: Ignore 'initializer overrides' warnings

["Philippe Mathieu-Daudé via" <qemu-devel@nongnu.org>]

We globally ignore the 'initializer overrides' warnings in C code
since commit c1556a812a ("configure: Disable (clang)
initializer-overrides warnings"). Unfortunately the ${gcc_flags}
variable is not propagated to Objective-C flags ($OBJCFLAGS).
Instead of reworking the configure script to test all supported
C flags in Objective-C and sanitize them, ignore the warning
locally with the GCC diagnostic #pragma (Clang ignores it).
