[PATCH] chainlint.pl: Extend regexp pattern for /proc/cpuinfo on Linux SPARC

[John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>]

On SPARC systems running Linux, individual processors are denoted with
"CPUnn:" in /proc/cpuinfo instead of the usual "processor NN:" so that
the current regexp in ncores() returns 0. Extend the regexp to match
lines with "CPUnn:" as well to properly detect the number of available
cores on these systems.
