package/libsysfs: bump to version 2.1.1

- Switch to github to get latest release
- Not an uploaded tarball, so autoreconf is necessary
- Update hash of license files (gnu.org license files are used since
  https://github.com/linux-ras/sysfsutils/commit/b69c2046ce8307804e91403643d43baad086feb3)
  Paragraphs are rewrapped, URLs and addresses have changed, and some
  additional explanation from gnu.org is added. It's still just (L)GPL
  though.
