Sprint: 2019-06

 Description   

We won't be compiling MariaDB Server any more so we can't link jemalloc at build time as this would cause issues with our plugin. We need to switch to LD_PRELOAD for the ColumnStore binaries (particularly ExeMgr and PrimProc).

As a side-effect this should also fix issues with jemalloc 5.x used in CentOS 8 and other newer platforms.

For MCOL-3702, added a bit of logic to figure out the right name for the jemalloc lib. Affects this as well.
