RFR: 8341024: [test] build/AbsPathsInImage.java fails with OOM when using ubsan-enabled binaries

[Matthias Baesken]

The jtreg test build/AbsPathsInImage.java fails with OOM when using ubsan-enabled binaries (on Linux x86_64).
Reason seems to be that the ubsan-enabled binaries are much larger than 'normal' product binaries.
(for debug binaries the test is already disabled)
Error is :

Especially the debuginfo file for libjvm.so gets HUGE, and needs a higher Xmx setting for this test.

At some later point in time, the test could be rewritten to use less memory when looking into the JDK image files.
