zram: add package to use compressed ram disk for swap
The busybox size is increased by 3.2KByte uncompressed on bcm47xx with
this commit.
This zram-swap automatically creates a zram device, a swap partition on
it and make the kernel swap pages to it.
Thank you Bastian Bittorf <bittorf@bluebottle.com> for idea and the
script.
