auto-disable preDexLibraries on CI systems

preDexing helps repeat builds run faster, but slows down builds that do
not have any caching.  CI builds start from scratch each time.  Turns
out that GitLab CI, Travis CI, Circle CI, and probably many others all
define the "CI" environment variable, so its easy to detect when running
in a CI environment.  This makes things a lot cleaner.
