libxl: config parser: Rebuild config file parser scanner (rerun flex)

The scanner from c/s 22735:cb94dbe20f97 is buggy and crashes with a
segmentation fault.  Rebuilding the sanner appears to fix the problem
so it appears that I somehow accidentally checked in a scanner which
doesn't correspond to the committed scanner source code.
