[RFC PATCH] macos: Allow coredump generation

[Philippe Mathieu-Daudé]

QEMU is allowed to generate coredump on other POSIX OSes,
bring that functionality to macOS. Admin users still need
to enable the kern.coredump sysctl manually running:

  % sudo sysctl kern.coredump=1

the normal users have to enable their shell running:

  % ulimit -c unlimited
