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.
