opencv updates for lbann (#6502)

Browse Source 
Add variants to control building of many 3rd-party modules in opencv.
They are enabled by default, which matches the defaults chosen by
opencv when these options are not set explicitly. This also updates
the lbann opencv dependency to disable most of these new variants by
default in order to build faster.
