sysfsutils: Update to 2.1.1

sysfsutils: Update to 2.1.1

- Update from 1.3.0 (2005) to 2.1.1 (2021)
- Update rootfile
- version 1.3.0 was from 2005. Version 2.1.0 was from 2006. No other updates have been
   carried out since 2006 until Feb 2021 when the repository was migrated from CVS
   to git. https://github.com/linux-ras/sysfsutils/releases
- Installed iso, that was created from build, into testbed vm system. All menu's opened
   and no issues found. Not 100% sure what to look for as I am not totally clear what
   the library would be used for or by which programs. Probably needs testing by someone
   who lnows what the sysfsutils library is used for.
- Ran find-dependencies on the original library system before build and then on the new
   library system after building and in both cases nothing was flagged up. So it looks
   like no other programs are linked to the library.
- pcmciautils required one of the sysfsutils include files to be available during the
   build. ./configure was modified to allow pcmciautils to find the include file
