Make mini-debug-info stripping pass on already stripped binaries

Browse Source 
Prebuilts may already be stripped.  Instead of requiring every stripped
prebuilt to be annotated with LOCAL_STRIP_MODULE := false, just make
the default (mini-debug-info) pass through already-stripped modules
without failing.
