Subject: [PATCH 3/3] selftests: kcmp build fails when invoked from kselftest target

kcmp Makefile doesn't have an explicit build rule. As a result,
kcmp build fails, when it is run from top level Makefile target
kselftest. Without the explicit rule, make works only when it is
run in the current directory or from selftests directory. Add an
explicit build rule to fix the problem. In addition, build fails
as it can't find kcmp.h. Fix it by passing CFLAGS.
