avsbus-control: Add system-specific scripts
The avsbus-control scripts differ between different machine
configurations. Rename the existing ones to witherspoon-* and
add the swift-* ones. Install the appropriate script depending
on the machine being built.
Tested: Built swift and witherspoon and verified that the scripts
rootfs/usr/bin/ were the ones for the machine being built.
