Support libraries (not just boot jars) that have hiddenapi

The build assumes (apart from one minor exception) that only modules
that are in the PRODUCT_BOOT_JARS list require processing as part of
the hiddenapi. Unfortunately, that is not true for android.test.base,
at least not when REMOVE_ATB_FROM_BCP=true.

This change adds a white list (containing android.test.base) of
additional modules that should be processed as part of the hiddenapi
and updates the hiddenapi.go file to use it.

It does not matter that android.test.base is a boot jar and in the
white list, the behavior is the same as it would be if it was only
in one.

Test: make REMOVE_ATB_FROM_BCP=true droid and make droid
