Linix binary ignores default SSL CA trust store /etc/ssl/certs

[lukaspustina]

The binary that is build for Linux using https://github.com/japaric/trust ignores the default Debian SSL CA trust store in /etc/ssl/certs. This issue is related to japaric/trust#81 and cross-rs/cross#119.

Current workaround is to set the environment variable SSL_CERT_DIR=/etc/ssl/certs.
