ypr0 - ypr1: dynamically move rockbox executable

This trivial patch wants to exploit /tmp filesystem to place
Rockbox executable. Why that? It will be then possible to
easily unlock & umount the storage partition, in order to provide
Rockbox itself a mean for RAW storage access. In turn, this will
allow a Rockbox-handled USB Mass Storage support, as well as other
goodies (storage info is one I can think of).

It takes way less than a second so it doesn't hurt boot time.
Moreover, YPR0/YPR1 targets have plenty (64MB) of RAM, so
the humble half meg executable won't hurt at all.
