requirements: Remove unnecessary version bounds from *.in.

This makes no changes to the locked versions in *.txt, but it reduces
duplicate information and gives us sane workflows for

* upgrading packages: remove some or all lines from *.txt and re-run
  `update-locked-requirements`;
* marking packages as intentionally held back: add a version bound
  to *.in with an explanatory comment.
