perf jvmti: Plug compilation into perf build

Compile jvmti agent as part of the perf build. The agent library is
called libperf-jvmti.so and is installed in default place together with
other files:

  $ make libperf-jvmti.so
    BUILD:   Doing 'make -j4' parallel build
    ...
    CC       jvmti/libjvmti.o
    CC       jvmti/jvmti_agent.o
    LD       jvmti/jvmti-in.o
    LINK     libperf-jvmti.so

  $ make DESTDIR=/tmp/krava/ install-bin
  ...
  $ find /tmp/krava/ | grep libperf
  /tmp/krava/lib64/libperf-jvmti.so
  /tmp/krava/lib64/libperf-gtk.so
