Pass NINJAJOBS if N_PARALLEL is defined

Now that MAKEFLAGS is defined at the beginning of the scriptlet,
there is no need to pass MAKEFLAGS as an envar to the scriptlet.
But still NINJAJOBS is not defined. In most cases, when we want
to use all cores, this is not a problem. But if N_PARALLEL is
defined, it needs to be passed. Note that we also pass
MAKEFLAGS in this case, because we use the old "wrt_xxx" function,
but it is not used.
