to avoid manual calculation of min and max values

adding one common definition that could be used in multiple files
under selftests.
there are also some defines for min/max scattered locally inside sources
under selftests.
this also prepares for cleaning up those redundant defines and include
kselftest.h instead.

changes in v2:
redefine min/max in a more strict way to avoid 
signedness mismatch and multiple evaluation.
is_signed_type() moved from selftests/kselftest_harness.h 
to selftests/kselftest.h.

Heh, reminds me of https://xkcd.com/927.

All of these #defines are available in tools/include/linux/kernel.h, and it's
trivially easy for selftests to add all of tools/include to their include path.
I don't see any reason for the selftests framework to define yet another version,
just fix the individual tests.

giving the reviews seems that patchset is useless.
still a confusing point for me; after adding tools/include to the
include path of selftes how we can differentaite between  #include
<linux/kernel.h> that under tools/include and one under usr/include.
