python3: Fix sysroot reproducibility

Fixes the reformatting of the sysconfigdata to be reproducible in the
sysroot as well as in the package. During this a bug was uncovered in
the way that the data was reformatted where it appears that python
cannot parse a single line of code over 40000 characters. To work around
this, pass a maximum with of "1" to pprint instead of sys.maxsize which
will cause it to wrap as often as possible and should keep it
reproducible.
