Christophe Leroy 6f8fb022ef perf: Completely remove possibility to override MAX_NR_CPUS
Commit 21b8732eb4 ("perf tools: Allow overriding MAX_NR_CPUS at
compile time") added the capability to override MAX_NR_CPUS. At
that time it was necessary to reduce the huge amount of RAM used
by static stats variables.

But this has been unnecessary since commit 6a1e2c5c26 ("perf stat:
Remove a set of shadow stats static variables"), and
commit e8399d34d5 ("libperf cpumap: Hide/reduce scope of
MAX_NR_CPUS") broke the build in that case because it failed to
add the guard around the new definition of MAX_NR_CPUS.

So cleanup things and remove guards completely to officialise it
is not necessary anymore to override MAX_NR_CPUS.

Fixes: e8399d34d5 ("libperf cpumap: Hide/reduce scope of MAX_NR_CPUS")
