Subject: [PATCH] serpbear: use a CA bundle without the compromised eMudhra
 roots

Mount patched-ca-bundle (see ca-bundle/) over /etc/ssl/certs so it stops trusting the compromised eMudhra intermediates (https://emudhra.we-have-a-problem.com). Node uses its built-in roots, so also switch it to OpenSSL's store with --use-openssl-ca.
