Subject: [PATCH] virt: pass emulator when getting domain capabilities
 from libvirt (#394)

On aarch64, for some emulated architectures like armv6l libvirt needs to
have the emulator path to properly return the domain capabilities.

Passing it will avoid virt.all_capabilities to fail on such
architectures.
