perf tools: Compile perf with libperf-in.o instead of libperf.a 

There's no need for perf build to use libperf.a,
we can use directly libperf-in.o.

The libperf.a stays as a target if needed:

  $ make libperf.a
  ...
    CC       util/pmu.o
    CC       util/pmu-flex.o
    LD       util/libperf-in.o
    LD       libperf-in.o
    AR       libperf.a
