Executing Spectrum Scale Install Package from /tmp could be blocked if /tmp is mounted with no_exec permissions

[mamuthiah]

It is not uncommon to find /tmp mounted with a no_exec option for security reasons. We currently copy the self extracting Spectrum Scale Install Package to /tmp on every node and execute it from there, which will fail if /tmp is mounted with the no_exec option.

To get around this problem, we should copy the package to some other directory on the root file system and extract from there.
