Load dynamic plugins with RTLD_GLOBAL flag

Browse Source 
The MPI MCA framework is another DSO-based plugin system which is
loading further plugins within our plugins. It does not work with
RTLD_LOCAL at the moment.

Enabling RTLD_GLOBAL for all dynamic plugins for now. If this leads
to problems, we can refactor and offer this load flag as an option.
