travis: add gcovr summary for GCOV build
This gives a more useful summary, sorted by descending % coverage, after the tests have run. The final numbers will give an idea if our coverage is getting better or worse. To keep the width sane we need to post process the file that the old gcovr tool generates. This is done with a mix of sed, awk and column in the scripts/coverage-summary.sh script. As quite a lot of lines don't get covered at all we filter out all the 0% lines. If the file doesn't appear it is not being exercised.

+# Summerise the state of code coverage with gcovr and tweak the output
+# to be more sane on Travis hosts. As we expect to be executed on a
+# throw away CI instance we do spam temp files all over the shop. You
+# most likely don't want to execute this script but just call gcovr
+# directly. See also "make coverage-report"
