Subject: [PATCH 1/2] selftests: Provide local define of min() and max()

to avoid manual calculation of min and max values
and fix coccinelle warnings such WARNING opportunity for min()/max()
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.
