License-Update: add GPLv3 text in README.licensing
Also:
- Drop upstreamed patch
- Backport an upstream patch to fix an issue with 'sfdisk'
- Use 'disable-hwclock-gplv3' explicitly.
Since commit 7a3000f7ba548cf7d74ac77cc63fe8de228a669e ("hwclock: use parse_date function") hwclock is linked
with parse_date.y from gnullib. This gnulib code is distributed with GPLv3.
So, we have to use '--disable-hwclock-gplv3' to exclude this code.
