[Runtime] Enable to support service port in WARP mode rules

Since the Chromium/Blink Access White List can not support to check service port pattern
in access rule, so need to treat it in runtime. This patch add a checking of
service port in WARP mode.

BUG=XWALK-3132
The Blink whitelist does not include the 'port' information, and this is the exactly thing this patch wants to add in.
