[libvirt] [PATCH v2] maint: Switch to xz compressed PAX release archives

[Andrea Bolognani]

This allows us to produce releases that are roughly a third in
size, have no limitation on path length, and are still readable
by all supported platforms.
---
Changes from [v1]:

  * Update all references to .tar.gz, including spec files,
    scripts and documentation (thanks Dan)
  * Fix typo lenght -> length (thanks Ján)
