Draft: scripts: Remove fragments

NOTE: This wasn't tested.

We've been able to upstream the configs needed for the arm64 chromebooks to the arm64 defconfig. Keeping these fragments around would only make us unintentionally rely on non-upstreamed configs. For situations where we do want to have additional configs (eg for the integration branch and archs like x86 where upstreaming to the defconfig isn't feasible), we've preferred the approach of keeping a commit with the defconfig changes in the linux repo.

For those reasons, remove the fragments.
