[Bionic][SRU][PATCH 3/4] selftests: lib.mk: cleanup RUN_TESTS define and make it readable

[Po-Hsu Lin]

From: "Shuah Khan (Samsung OSG)" <shuah at kernel.org>

BugLink: https://bugs.launchpad.net/bugs/1812352

Refine RUN_TESTS define's output block for summary and non-summary code
to remove duplicate code and make it readable.

cd `dirname $$TEST` > /dev/null; and cd - > /dev/null; are moved
to common code block and indentation fixed.
