Support sys-crates build script dependencies. (#341)

Sys-crates may produce "cargo:var=value" output that must be translated
into DEP_CRATE_NAME_VAR=VALUE environment variable that is then must be
made visible to all direct dependent crates build files.

This in particular is used by openssl and openssl-sys crates.
