perf_counter tools: Fix unknown command help text

Arjan reported this error when entering an unknown command to perf:

$ perf start
fatal: Uh oh. Your system reports no Git commands at all.

The Git code expects there to be perf-* commands - but since Perf
is a 'pure' utility with no dash commands anymore, this old assumption
of Git does not hold anymore. Remove that error check.
