Subject: [PATCH] perf: convert usages of profile_cpu in builtin-top.c to use cpu_list

profile_cpu was left over from an earlier implementation that supported
running perf top on a single CPU. profile_cpu was no longer set by
any switch and usages of it resulted in dead code.

Instead, convert the code to use cpu_list, which is set by the -C <cpu_list>
option.

Also improved the printing of nr_cpus and cpu_list by correcting the plurals.
