kbuild: simplify command line creation in scripts/mkmakefile
Assuming we never invoke the generated Makefile from outside of
the $(objtree) directory, $(CURDIR) points to the absolute path
of $(objtree).
BTW, 'lastword' is natively supported by GNU Make 3.81+, which
is the current requirement for building the kernel.
