Log message:
security/ocaml-safepass: Update to 3.1

Upstream does not publish NEWS, but it appears changes are:
  - bugfixes (listed as "remove warnings" :-)
  - change from jbuilder to dune

Changing to dune -- which 3.0 is documented to use but apparently does
not -- makes the package, which is configured to use dune, build.
(Calling this an improvement without further understanding.)

Log message:
Recursive revbump associated with update of ocaml.

Also change of mk/ocaml.mk to lang/ocaml/ocaml.mk.

Log message:
security: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes
