OSHMEM: Fix issue with incorrect mca variables registration

Few components had wrong mca variables registration procedure
List of them:
- atomic basic and mxm
- spml yoda and ikrit
Two mca variables as runtime_api_verbose and runtime_lock_recursive change
names to oshmem_api_verbose and oshmem_lock_recursive otherwise they
were not shown by oshmem_info tool.
