Sam Bobroff 99597ceda0 selftests/powerpc: Improve tm-resched-dscr
The tm-resched-dscr self test can, in some situations, run for
several minutes before being successfully interrupted by the context
switch it needs in order to perform the test. This often seems to
occur when the test is being run in a virtual machine.

Improve the test by running it under eat_cpu() to guarantee
contention for the CPU and increase the chance of a context switch.

In practice this seems to reduce the test time, in some cases, from
more than two minutes to under a second.

Also remove the "progress dots" so that if the test does run for a
long time, it doesn't produce large amounts of unnecessary output.
