perf: pack the libperf-jvmti plug-in to perf RPM

libperf-jvmti.so hasn't been built as part of perf RPM in the previous
openEuler releases. This patch will enable the building and packing of
jvmti shared library by default. It should faciliate the JDK user to profile
Java application after installing the perf.
