chainlint.pl: fix incorrect CPU count on Linux SPARC

Browse Source 
On SPARC systems running Linux, individual processors are denoted with
"CPUnn:" in /proc/cpuinfo instead of the usual "processor : NN". As a
result, the regexp in ncores() matches 0 times. Address this shortcoming
by extending the regexp to also match lines with "CPUnn:".
