archiver.bbclass: Drop tarfile module to improve performance

Browse Source 
* The tarfile module doesn't support xz options or environment varible
  XZ_DEFAULTS, this makes do_ar_patched incrediblely slow when the file is
  large, for example, chromium-x11 is about 3GB:
  - "bitbake chromium-x11 -car_patched" hasn't been done after 3 hours on my
     host, I checked the partial tar.xz file is only 1.5GB, so maybe more than 6
     hours is required to complete the task.

  - Now only less than 4 minutes is needed on the same host.

* Need add xz to HOSTTOOLS when archiver.bbclass is enabled and compression is xz.
