src: check node_extra_ca_certs after openssl cfg

I recently discovered that the custom NodeJS specific OpenSSL
config section in openssl.cnf would not be respected, if the
environment variable `NODE_EXTRA_CA_CERTS` was set.

This happens even if it contains an invalid value, i.e no actual
certs are read.

Someone suggested moving the checking of extra ca certs to after
the OpenSSL config is read, and this seems to work.
