Handle the case when there is no processor info in `/proc/cpuinfo` 

`grep -c` would correctly output "0", which is handled specially later
on, but would also exit with a nonzero status which would abort the
script. Piping the output to `wc` to do the counting makes the exit
status of grep irrelevant.

Fixes #447
