Fix the wrong parameter when calling read_metadata_from_package().

The call to read_metadata_from_package() is broken due to being passed
an invalid pointer (ZipArchiveHandle vs ZipArchiveHandle*). It's
introduced when switching from minzip to libziparchive. Compiler didn't
complain, because ZipArchiveHandle is typedef'd as void*, which legitly
accepts a void**.

Also clean up secure_wipe_partition() logs a bit by using android-base
logging.

Bug: 36427762
Test: Send a wipe package.
