RFR: 8044772 TempDirTest.java still times out with -Xcomp

[Staffan Larsen]

This test launches four other VMs, thus taking a very long time to run with -Xcomp. The real change here is to increase the timeout of the test, but I have also added some logging so that it is possible to see for how far along the test has come if it times out.
