Update minimum nanokernel footprint benchmark

Browse source 
Revises the nanokernel footprint benchmark project so that the
minimum x86 configuration explicitly excludes support for the
system timer. (This doesn't actually save any memory, since timer
support was already being excluded; however, the project now makes
this lack more apparent, and does it the same way as the minimum
microkernel benchmark project does it.)
