Make "low ram device" a readonly system property 

This lets components outside the Zygote / Android resource regime
know whether this is considered a "low ram" device.

Set the property [ro.config.low_ram] to "true" if the device is to be
considered low-ram.  Any other property string (or its absence) will
be interpreted as meaning this is a normal larger-ram device.  The
"true" string must be all lower case.
