[PATCH 2/4] HS20: Fix for TrustRoot path for PolicyUpdate node in PPS MO

[Ilan Peer]

From: ASHUTOSH NARAYAN <ashutoshx.narayan at intel.com>

In the original code, the TrustRoot path is "PolicyUpdate/TrustRoot", which is
incorrect. The TrustRoot path is required to be "Policy/PolicyUpdate/TrustRoot"
as defined in Section 9.1 of the spec Hotspot2.0_rel_2(version 5.0). This patch
corrects the path to "Policy/PolicyUpdate/TrustRoot".
