Qt: Run macdeployqt twice

Run macdeployqt twice. This seems silly, but since we don't have a direct reference to QtSvg,
it doesn't deployed directly from the main binary (only indirectly from iconengines), and
the libqsvg.dylib imageformat plugin does not get deployed. The second time round, the Svg
module is found, and thus imageformats gets deployed.

Fixes controller images not being displayed in Mac builds.
