getOfflineLicenseKeySetIds() respects plugin security level.

Browse Source 
[ Merge of http://go/wvgerrit/208155 ]

The MediaDrm plugin API getOfflineLicenseKeySetIds() was listing
both L1 and L3 offline licenses.  While this is generally acceptable,
apps might force set L3 via the setStringProperty(), which should
cause the DRM plugin to behave as if it is L3 only.

This change will cause the WVDrmPlugin list L3 only if the app had
set the security level to L3.
