blktrace: Use number of online CPUs
Currently, blktrace uses _SC_NPROCESSORS_CONF to find out the number of
CPUs. This is a problem, because if you reduce the number of online
CPUs by passing kernel parameter maxcpus, then blktrace fails to start
with the error:
FAILED to start thread on CPU 4: 22/Invalid argument
FAILED to start thread on CPU 5: 22/Invalid argument
...
The attached patch fixes it to use _SC_NPROCESSORS_ONLN.
