Merge branch 'js/ci-leak-skip-svn'

Dscho observed that SVN tests are taking too much time in CI leak
checking tasks, but most time is spent not in our code but in libsvn
code (which happen to be written in Perl), whose leaks have little
value to discover for us.  Skip SVN, P4, and CVS tests in the leak
checking tasks.

* js/ci-leak-skip-svn:
  ci: skip CVS and P4 tests in leaks job, too
  ci(*-leaks): skip the git-svn tests to save time
