Subject: [PATCH] Let scl_source behave when "-e"/errexit is set (#35)

Jenkins pipelines, among other things, use `set -e` (aka bash `errexit`) to abort on "errors". So when `source scl_source` is used in a pipeline, the way the exit code from `scl_enabled` is checked via `$?` causes an unintended abort of the pipeline. (Workaround is to use `set +e; source scl_source ...; set -e`.)

This trivial change to `scl_source` simply changes how the value of `scl_enalbed` is checked to be friendly to `errexit`.
