Subject: Travis: use --concurrency=multiprocessing only on build tests (#6872)

On a local workstation, it seems that tracking multiple processes during
coverage may result in malformed coverage reports for unit tests and not
for build tests.

Given that multiple processes make a difference in coverage mainly for
build tests, try to disable the tracking for unit tests to see if we get
more stable coverage results.
