Subject: [PATCH v1] 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.
