Delete duplicate linux lock/wipe scripts (#25611)

#22544

The Linux wipe/lock scripts have lived as duplicated in two locations
for a long time. This removes the copy that isn't used.

The remaining scripts in the `ee/server/service/embedded_scripts` folder
are pulled in here.

https://github.com/fleetdm/fleet/blob/12d8017ff905555feb0053e7a09eded404b5e8f1/ee/server/service/hosts.go#L499-L508

It looks like the `wipe` script in `scripts/mdm/linux` was even slightly
out of date compared with the one in the `ee/` folder.
