[bug#49867] [PATCH v2 13/31] gnu: Add ocaml-mirage-crypto.

[Julien Lepiller]

Trying to build ocaml-mirage-crypto, I get errors during the tests:

ocamlopt tests/test_symmetric_runner.exe (exit 2)

Error: Files
/gnu/store/id3dchcsw5gijsnn73kw5sn9ymjj90ai-ocaml-eqaf-0.7/lib/ocaml/site-lib/eqaf/bigstring/eqaf_bigstring.cmxa
and
/gnu/store/id3dchcsw5gijsnn73kw5sn9ymjj90ai-ocaml-eqaf-0.7/lib/ocaml/site-lib/eqaf/eqaf.cmxa
make inconsistent assumptions over implementation Eqaf

this seems to indicate Eqaf did not build properly? Does it build for
you?

also, minor but there's a typo in the synopsis "provding" ->
"providing".
