FS#1648 - Please build busybox swapon with discard support

Busybox supports swap discard mounting since late March 2014[1]. Zram suports TRIM/discard since early April 2014[2]. On OpenWrt systems with zram-swap, being able to mount the zram swap space as discardable would be quite beneficial, since compressed freed pages would be immediately returned to the system.
