When running makeparallel in non-ninja mode, which is used when running
kati with USE_GOMA=true, convert -j to a reasonable parallelism value
the same way ninja does.

Test: make -C build/make/tools/makeparallel makeparallel_test

Ninja stops parsing top level options after -t is used to select a
tool. Put any inserted command line options at the beginning of the
command.

Allow makeparallel to pass better -j and -k arguments to ninja if the
first argument to makeparallel is --ninja. Uses getopt to parse
MAKEFLAGS to get values for --jobserver-fds, -k, and -j, and uses the
result to not pass any -j argument to ninja for make -j with no number,
and pass -k0 to ninja for make -k.
Also improve the test makefile to provide many more tests.

makeparallel communicates with the GNU make jobserver
(http://make.mad-scientist.net/papers/jobserver-implementation/)
in order claim all available jobs, and then passes the number of jobs
claimed to a subprocess with -j<jobs>.
