perf tools: Remove verbose build messages for the python binding

Also now it builds it in a well known location:

[acme@felicio linux]$ rm -rf ../build/perf/
[acme@felicio linux]$ mkdir ../build/perf
[acme@felicio linux]$ make -j2 O=~acme/git/build/perf -C tools/perf/

[acme@felicio linux]$ ls -la ../build/perf/python/
