dbus-execute: make transfer of CPUAffinity endian safe (#12711)
We store the affinity mask in the native endian. However, over D-Bus we
must transfer the mask in little endian byte order.
This is the second part of c367f996f5f091a63f812f0140b304c649be77fc.
(cherry picked from commit 75e40119a471454516ad0acc96f6f4094e7fb652)
