Michael Paquier bba2e66aec Fix corner case with PGP decompression in pgcrypto ...

A compressed stream may end with an empty packet, and PGP decompression
finished before reading this empty packet in the remaining stream.  This
caused a failure in pgcrypto, handling this case as corrupted data.
This commit makes sure to consume such extra data, avoiding a failure
when decompression the entire stream.  This corner case was reproducible
with a data length of 16kB, and existed since its introduction in
e94dd6a.  A cheap regression test is added to cover this case.

Thanks to Jeff Janes for the extra investigation.
