[SLOF] [PATCH 2/9] obp-tftp: Make sure to not overwrite paflof in memory

[Thomas Huth]

The obp-tftp package is currently using an arbitrary large value
as maximal load size. If the downloaded file is big enough, we
can easily erase Paflof in memory this way. Let's make sure that
this can not happen by limiting the size to the amount of memory
below the Paflof binary (which is close to the end of the RAM).
