Skip test failing on GNU/Hurd when writing on /dev/zero or
/dev/random. On different GNU/Hurd installations writing to either one or
another would fail. Currently writing to /dev/random results in the message
"Computer bought the farm" and exit status 1

* Team upload.
* When a file with restricted permissions is compressed, the resulting file
inherits the umask of the user for the time of the compression. This will
usually lead to surprising and too relaxed permissions. This update adds
fix-file-permissions-on-compression.patch to make sure the compressed file
is not group or world readable for the duration of the compression. Closes: #981404
