Add SSL_CERT_DIR for all embedded Go services

We have Go programs that use Go's own crypto/tls library instead of OpenSSL. We can tell crypto/tls about /opt/gitlab/embedded/ssl/certs/ by setting SSL_CERT_DIR=/opt/gitlab/embedded/ssl/certs/.

This addes this value to all of the env nodes for the approriate services that use Go.
