p5-dbd-mysql: Fix variant conflicts issues and update perl versions

Fix issue where multiple variant conflicts were being set as a single
  conflict. Fixing this also allowed for the removal of the
  active_vartiants workaround.

  - fix variant conflicts
  - remove active variants workaround
  - fix typos
