RFR(S): 8223396: [TESTBUG] several jfr tests do not clean up files created in /tmp

[Leonid Mesnik]

Hi

Have you considered fixing makefiles to set 'java.io.tmpdir' described the https://bugs.openjdk.java.net/browse/JDK-8213214 <https://bugs.openjdk.java.net/browse/JDK-8213214>
rather than adding new method and fixing individual tests?
