8353231: Test com/sun/management/OperatingSystemMXBean/GetProcessCpuLoad still fails intermittently

[kevinjwalls]

Test com/sun/management/OperatingSystemMXBean/GetProcessCpuLoad still fails intermittently.
On failure, 10 attempts with sleep(200) each time, only read -1 from mbean.getProcessCpuLoad().
The method is documented to return -1 when info is not available, but want to avoid the test accepting a -1 and masking real problems.

Test failures are happening when multiple CPU load reding tests ran on the same host, at the same second.
Add a TEST.properties file containing: exclusiveAccess.dirs=.
