dev-ml/camomile: ocaml-4.09 compat fixes

Existing ebuild will not build with ocaml-4.09, only with older versions
that have an outstanding GLSA (202007-48). ocaml-4.09 is being
stabilized now.  This commit just uses the existing workaround/fix in
b.g.o and updates the ebuild to EAPI=7.

Note that EAPI7 required modifying an existing patch so it will apply
with -p1; should still work with the old ebuild that uses epatch.

Updated to address feedback in https://github.com/gentoo/gentoo/pull/16964
