update-binary: Selectively remove Google's SuW

* This is done based on the total memory as reported by /proc/meminfo
* If the memory in the MemTotal field is less than 1572864 kB (1.5 GB),
  then Google's SuW is removed as a precaution, as it is known to crash
  on devices that don't have much memory available to use
* Thanks to cdesai for the solution idea
