removeOfflineLicense() respects plugin security level.

[ Merge of http://go/wvgerrit/208116 ]

The MediaDrm plugin API removeOfflineLicense() would check both
L1 and L3 for the offline license.  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 only remove L3 key set IDs while
in L3 mode.  L1 key set IDs in this case will be treated as non-existing.
