So, what should I do.....try applying the new tiles to the floor as is
(over the old black mastic), or buy some Latex Floor Primer to paint
over the black mastic?

Neither until you prep the floor properly...

Agreed- self stick tile (which I would never use, personally- seen too
much float around), needs a smooth floor to work. Any irregularities
will telegraph through, the joints won't be tight, etc. Anybody know if
self-stick will stick to self-leveling floor compound?
