RFR: JDK-8255734: VM should ignore SIGXFSZ on ppc64, s390 too

[Thomas Stuefe]

Hi,

may I have reviews please for this small fix.

We willfully ignore SIGPIPE and SIGXFSZ, since their default action is to terminate the VM. However, SIGXFSZ handling was missing for linux ppc64, s390 and AIX. 

Note that this is a minimal patch, with the explicit aim of making backporting simple. This whole coding will change a lot with JDK-8255711, so I did refrain from changing much more code.

Thanks, Thomas
