[8u] RFR (XS) 8265978: make test should look for more locations when searching for exit code

[Aleksey Shipilev]

This is 8u-specific build system bug:
   https://bugs.openjdk.java.net/browse/JDK-8265978

I believe there is a little omission in the code that checks the exitcode.
See the bugreport for more details.

8u fix:
   https://cr.openjdk.java.net/~shade/8265978/webrev.8u.01/

Testing: failing tests now report non-zero exitcode
