[xad] Checksum failed on zip file

[ci-macpaw]

Mozbugbox (mozbugbox):

The attached zip was created by a cloud storage service (pan.baidu.com).

When unpacking with unar, checksum failed messages were spit out. However, the extracted files seemed to be fine.

When unpacking with unzip, there were no error except the encoding of the filenames were messed up. The actual filename encoding in the archive was gbk.

lsar -t baidu-pack.zip also give out checksum failed error.
