Repair any mis-directed android-1.0 annotated tagsv1.0.6

The initial open source release of the Android 1.0 platform had
some problems with its Perforce->Git imports.  Google was forced
to rewrite some history to redirect users onto more stable upstream
sources and correct errors in the imports.

Not everyone has the correct android-1.0 tags, as some users did
manage to fetch the platform early, before the mirror sites crashed
and the history was rewritten.

This change is a band-aid to ensure any stale android-1.0 tags are
get updated to the corrected version.  It should be backed out at
some point in the near future, when we can be fairly certain that
everyone has the correct android-1.0 tags.
