RFR: JDK-8297184: Test runtime/ErrorHandling/TestSigInfoInHsErrFile.java is failing [v3]

[Thomas Stuefe]

> https://bugs.openjdk.org/browse/JDK-8296906 added a new test that artificially crashes the VM with a known signal/code/crashaddress and checks that we see those informations precisely in the hs-err file. It did this for SIGSEGV and SIGFPE.
> 
> SIGFPE, however, is problematic. We fall back to pthread_kill() if we cannot trigger a real FPE fault. In that case the code will be SI_KILL and the sending frame will be pthread_kill(). 
> 
> Since we cannot guarantee that a real signal is sent, I opted for just removing the part of the test that tests FPE. The other part, testing SIGSEGV, is enough to cover what the test should cover.
