`kernel.shmmax` and `kernel.shmall` updated to kernel defaults on IBM Z
Previously, applications that required a large amount of memory in some cases terminated unexpectedly due to low values of the `kernel.shmmax` and `kernel.shmall` parameters on IBM Z. This update aligns the values of `kernel.shmmax` and `kernel.shmall` with kernel defaults, which helps avoid the described crashes.

------- Comment From epasch.com 2017-11-29 09:48 EDT------- The kernel.shmmax and kernel.shmall = 268435456 can be removed. The same reason as given for the general file at https://github.com/fedora-sysv/initscripts/commit/e3784a1aefb3f38a5a3f9ae69b3feff9c8ef5610#diff-5e6436c816034c6fd3829b55f323caad applies here as well. It doesn't make sense to set the defaults twice.
