workaround for ca-certificate-utils-20150402-1

For some reason, ca-certificate-utils-20150402-1 removes
/etc/ssl/certs/ca-certificates.crt, which is needed by
curl, the http(s) backend for curl. Until either curl
is reconfigured or ca-certificates.crt is restored,
we must create it ourselves.

This fixes issue #10.
