Upstream patch #28 from git master. Will be present in next release.


Use LANG=C to parse sfdisk output

This will prevent failure to parse output of in non-C locales leading to
failure to resize partition.

Alternative would be to use sfdisk --dump, but this misses some
importants informations such as the sectors size

Reported in:
https://bugs.launchpad.net/cloud-utils/+bug/1860479

This was tested on centos7 with sfdisk 2.23.2 and
centos8 with sfdisk 2.32.1
