perf tools: Move syscall and arch specific defines from perf.h

Into new perf-sys.h header.

The main reason is to separate system specific perf data
from perf tool stuff, so it could be used in small test
programs, as requested Peter:

  http://lkml.kernel.org/r/20140502115201.GI30445@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

This separation makes the perf.h header more clear.
