recovery:updater: Changes to support 32->64 bit upgrades

We now support upgrading from 32 to 64 bit builds. The check for device to
package compatibility now takes into account if the product name on the
device vs the product name on the upgrade build differs only by the _32
or _64 trailing chars. In addition we also force compile the updater binary
as 32 bit executable so that it can run on the 32 bit build we are upgrading
from.
