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
