Bug 1059814 - Deploy script: Remove unnecessary sys.path additions

The directory of the currently running script is already on the path:
https://docs.python.org/2/tutorial/modules.html#the-module-search-path
...so adding it is unnecessary.

In addition, I don't believe we need the treeherder-service directory on
the path, since we don't directly import anything from there.
