Log Message:
s6-networking: update to 2.7.0.0. Changes:

- Bugfixes.
- Better API for s6-tlsc-io: now "s6-tlsc-io 6 7" is the equivalent
  of s6-ioconnect with TLS, and can be used interactively as a client
  program to talk to TLS-tunneled services.
- The -K option for TLS programs now set a timeout for the whole handshake.
- The -h option for s6-tcpclient and s6-tcpserver-access now indicates
  /etc/hosts should be consulted before DNS.
