Josef Söntgen 4c8369ab1b tool/depot/publish: support multiple threads in xz
Introduce 'XZ_THREADS' to override the default number of threads used
for compression, which is still set to '1'. As using multiple threads
will increase the amount of memory needed during the compression and
potentially influences the size of the created archive, setting the
variable limits the impact.

Fixes #3431.
