Drop tools that either aren't installed by default anymore, or don't
make sense in a netboot environment:
- readprofile: read /proc/profile which we don't enable in the kernels
- tunelp: tune line printer settings
- mcookie: manage magic cookies used by X11 (xauth)
- script: used to record interactive shell sessions
- scriptreplay: run the recording of script (see above)
- fdformat: format floppy disks which we don't enable in the kernels
- cytune: control old serial cards which we don't enable in the kernels
- tailf: use `tail` instead
- write: broadcast messages to other users logged in
- isosize: get details for ISO images
We can probably trim even more, but let's start here.
