[PATCH] Makefile: preserve --jobserver-auth argument when calling ninja |

Qemu wraps its call to ninja in a Makefile. Since ninja, as opposed to
make, utilizes all CPU cores by default, the qemu Makefile translates
the absense of a `-jN` argument into `-j1`. This breaks jobserver
functionality, so update the -jN mangling to take the --jobserver-auth
argument into considerationa too.
