Use guiles native sort and record. Fix #373809.

Slib 3a4 changed the way to determine whether to use natively supported
features or the ones provided by slib. This leads to several problems:
* some code creates a record with one implementation and code uses it
  with the other implementation
* slibs sort does not seem to work with guile 1.6.8 arrays and even
  exposes a bug in those arrays

Return to the status quo by removing all (require 'sort) and (require
'record). GnuCash depends on Guile >= 1.6 which should feature that.
