[libvirt] [PATCH 2/2] Add stat-time to get timestamps

[Hendrik Schwartke]

!!! DON'T PUSH until stat-time lgpl 3 issue is fixed
!!! To tests this change lgpl version to 3 in bootstrap.conf:176

stat-time offers a much cleaner way of getting timestamps than
the current implementation. Therefor the implementation is changed.
