vold: Enable legacy support for wrapped key

Legacy wrapped key support was dropped while merging changes
to support multiple versions of dm-default key driver in kernel.
Fix this by calling legacy API to check wrapped key support for
metadata encryption.

 system: vold: Use wrapped key for metadata encryption

Wrapped key feature is needed for better security of encryption keys and
to
ensure data integrity when crypto key cache is cleared during reset
operation
of storage/crypto hardware.

Original patch:
https://source.codeaurora.org/quic/la/platform/system/vold/commit/?h=LA.QSSI.11.0.r1-05600-qssi.0&id=c480f913e6abc2757c0d79afba5a3df1c4adc731
[Pig]: Clean up all deprecated codes that were removed during latter
merge.
