procps: Add patch to fix errors that prevent build with gettext-0.22

- Gettext earlier than 0.21 would still build when it found errors in language files etc.
   With gettext-0.22 if it finds any errors it now stops.
- There were two lines in the french po file in procps that had erros in them. procps have
   raised a commit to fix those. The patch included here carries out that commit.
- Update of rootfile not required.
- This patch will not be needed when the next update of procps occurs.
