Jelle Raaijmakers a44978b9b0 LibC: Fix %n conversion specifier in scanf() format ...

Also add a test to prevent this from happening again. There were two
bugs:

* The number of bytes just after processing the last value was written,
  instead of the number of bytes after skipping remaining whitespace.
  Confirmed by testing against GNU's `scanf()` since the man page
  leaves something to be desired.

* The number of bytes was written to the wrong variable argument; i.e.
  the first argument was overwritten.
