bin/chroot-maint: Force `--no-merged-usr'.

Otherwise things go excitingly wrong.  The crosstools tree has split
root and `/usr', so when we try to copy the tools into the target
chroot, the corresponding paths start fighting each other, and only one
`.../lib/x86_x64-linux-gnu' symlink can win.

Also, you can't make good package builds with merged `/usr'.

Also also, it's just a really bad idea.
