zip: Remove last remnants.

We still have "unzip" for some parts of the build involving attributes,
but "zip" we no longer have in-tree, so remove these last bits of it.

Fixes #18476.

-If flag & EB_BE_FL_NATURAL, the data is not compressed; this optimisation is
-necessary to prevent wasted space for files with small attributes (which
-appears to be quite common on the Advanced Access DR9 release).  In this
-case, there should be ( ef_size - EB_L_BE_LEN ) bytes of data, and full_size
-should equal ( ef_size - EB_L_BE_LEN ).
-
-If the data is compressed, there will be ( ef_size - EB_L_BE_LEN ) bytes of
-compressed data, and full_size bytes of uncompressed data.
-
-If a file has absolutely no attributes, there will not be a 'Be' extra field.
-
-The uncompressed data is arranged like this:
-
-attr_name\0 - C string
-struct attr_info (big-endian)
-attr_data (length in attr_info.size)
