AndroidIA: REVERTME: Fix issue with UID range.

If netd doesnt have support for providing UID range,
updating of the rules fails due to invalid UID.

This patch fixes the issue by adding support for
handling the UI provided using UID_START and UI_END
fields.

JIRA: https://01.org/jira/browse/AIA-236
Test: If wifi is disabled/enabled , it should still continue to work.
