perf test java symbol: Additional libperf-jvmti.so path check

perf test java symbol: Additional libperf-jvmti.so path check

If perf is built into an output directory then so is
libperf-jvmti.so.

If `perf test` is run from that directory then PWD needn't also be that
directory meaning libperf-jvmti.so won't be found and the test skipped.

Add an additional check for libperf-jvmti.so in the same directory as
the perf binary for this case, this avoids the test skipping.
