[Libguestfs] [PATCH v3 1/3] v2v: OVF: improve get_ostype mappings

- consider CentOS as RHEL, since oVirt has no CentOS OS mappings, and
  CentOS is derived from RHEL
- use rhel_6_9_plus_ppc64 for RHEL 6 >= 6.9 on ppc64/ppc64le, while
  rhel_6_ppc64 for RHEL 6 < 6.9
- use rhel_7_s390x for RHEL 7 on s390x
- use sles_11, and sles_11_ppc64 for any SLES greater than 11, not only
  11
- use sles_12_s390x for SLES 11+ on s390x
- use ubuntu_16_04_s390x for Ubuntu 16.04+ on s390x
- use other_linux_ppc64 for any unmapped Linux distro on ppc64/ppc64le
- use other_linux_s390x for any unmapped Linux distro on s390x

[Libguestfs] [PATCH v3 2/3] v2v: OVF: write ovirt:id attribute for the OS in OVirt flavour

When writing the OVF in OVirt flavour, add a ovirt:id attribute to the
OperatingSystemSection tag: this attribute represents the numeric value
of the ostype ID, which is ignored by oVirt when parsing OVFs in API
mode.

[Libguestfs] [PATCH v3 3/3] v2v: OVF: fix ovf:id for VirtualSystem in OVirt flavour

When writing the OVF in OVirt flavour, write the actual UUID of the
VM as ovf:id attribute for <VirtualSystem>, instead of a dummy value.

Suggested by Arik Hadas in
https://www.redhat.com/archives/libguestfs/2018-April/msg00005.html

Sadly, OVF schema says ovf:id is reqiured. But since the generated OVF
