[PATCH] virtiofsd: Call qemu_init_exec_dir

[PATCH] virtiofsd: Call qemu_init_exec_dir

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

Since fcb4f59c879 qemu_get_local_state_pathname relies on the
init_exec_dir, and virtiofsd asserts because we never set it.
Set it.
