Nocrypto patches for compatibility with sexplib/ppx_sexp_conv > v0.11.0

ppx_sexp_conv v0.11.0 compiles successfully, but contains an undesired
dependency on base, and is thus still marked as conflicting. This is
fixed in ppx_sexp_conv v0.11.1.

This commit submits @gasche's fixes from

+Subject: [PATCH 1/4] add missing runtime dependencies in _tags
+
+Binaries in <bench/*>, <tests/*> depend on ppx_sexp_conv's runtime
+library within ppx_sexp_conv.
+
+The packed modules <src/nocrypto.cm{x,o}> also depend on the package
+ppx_sexp_conv: its presence at pack-creation time influences the
+generated .cmi interface, see
+
+  https://github.com/ocaml/opam-repository/pull/11628#issuecomment-375697444
+
+Note: the package ppx_sexp_conv.runtime-lib would suffice, but it is
+only available as such under recent ppx_sexp_conv versions, so its
+explicit use would make the build description (needlessly)
+incompatible with older ppx_sexp_conv versions.
