system/extra: include more of what you use.

This is a reland of aa24bc89b78a5981df7618bdef78b7b49ffad14d which was
reverted in 291e20dab39783c7074191ff2d2de9b86465c10f because it broke
the git_master-gpl builder.

This version of the change uses crypto.h as a proxy for mem.h because
it'll work in both BoringSSL and OpenSSL.
