* Skip building docs when building openssl
* See https://github.com/openssl/openssl/issues/8170
* The install_sw target exists since 1.0.0 or earlier:
https://github.com/openssl/openssl/blob/OpenSSL_1_0_0-stable/Makefile.org
* Re-enable ssldir creation target for openssl install
Prior commit attempts to shorten install by omitting documentation install,
however an additional target is needed to get the conf dirs for capturing the
PEMs et al.
* OpenSSL 1.1+ needs the extra install_ssldirs target to install certificates
* Add Darwin-arm64 and Linux-aarch64 for truffleruby-dev and truffleruby+graalvm-dev
