Revert "kernel: restore scripts in the sysroot"

This reverts commit 6a6735cb98.

The module class already ensures the scripts are rebuilt correctly. Running
this at sstate installation time is problematic since it can require the
cross compiler. Adding such a dependency would cause issues of its own.
