Nathan Hjelm 8b5810f7f7 mca/base: add priority output to mca_base_select
The mca_base_select function uses returned priorities to select the
best component/module. This priority may be of use to the caller so
pass that information back in an optional argument. If the priority is
not needed pass NULL.
