[PULL 39/40] Set icon for QEMU binary on Mac OS

[Paolo Bonzini <pbonzini@redhat.com>]

From: John Arbuckle <programmingkidx@gmail.com>

Before switching the build system over to Meson, an icon was
added to the QEMU binary on Mac OS. This patch adds back that
feature; it piggybacks on the existing scripts/entitlement.sh,
which already does in-place changes to the executable on Darwin.
