Fix guile.

- The date reproducibility issue was not actually set to any date, which
  could cause issues in the fiture, fix that sed.
- Fix a reproducibility issue (under QEMU), where the ordering of files
  within libguile can be random. This also affects guile binary so we
  need to rebuild that.
- Some change in kernel versions means that guile binary is
  significantly different in newer kernel versions. Because we cannot
  know the version of the host under chroot mode we must disable guile
  checksum entirely.
- Update checksums accordingly.
