remove unused archs 

I am not using nor need arm64 and windows. Removing these from the
Makefile. If you see this message and feel like they should be added
back (or different archs), ping me.

Undocker has no dependencies outside Golang stdlib.
Installation
------------
We recommend using [officially released binaries][3]. To build the project
instead, run:
```
$ make undocker
```
The number of officially released binaries is quite limited. If you'd like me
to expand a list, please contribute a patch to the Makefile.
Usage: convert docker image to rootfs
