[PATCH ima-evm-utils] ci: cleanup build.sh test log output

[Mimi Zohar <zohar@linux.ibm.com>]

Unlike the original ima-evm-utils ima_hash.test and sign_verify.test
selftests, kernel tests may fail for any number of reasons (e.g. kernel
config, permissions, missing applications, test infrastructure).  For
these tests, the full test log is needed to analyze the failure.

Create a phony target in tests/Makefile.am named "check-logs". Based on
test name, output different amounts of the test log.

[Applies on top of Roberto's "v3 Support testing in new enviroments"
 patch set.]
