ath79: add low_mem to tiny image
Devices with SMALL_FLASH enabled have "SQUASHFS_BLOCK_SIZE=1024" in
their config. This significantly increases the cache memory required by
squashfs [0]. This commit enables low_mem leading to a much better
performance because the SQUASHFS_BLOCK_SIZE is reduced to 256.
Example Nanostation M5 (XM):
The image size increases by 128 KiB. However, the memory statisitcs look
much better:
Default tiny build:
------
MemTotal: 26020 kB
MemFree: 5648 kB
MemAvailable: 6112 kB

low_mem enabled:
