runtests: add a function to test if IPv6 is available

Previously, checkportisavailable returns True if the port is free either on
IPv4 or IPv6, but the hg server only uses IPv4 by default. That leads to
issues when IPv4 port is not free but the IPv6 one is.

To address that, run-tests should stick with either IPv4 or IPv6. This patch
adds a function similar to checkportisavailable to test if IPv6 is
available, and assigns the result to a variable.

The new function was tested in a Linux system script with the following
steps:

  1. Run "ip addr del ::1/128 dev lo" to delete lo's IPv6 address,
     Confirm checkipv6available() returns False.
  2. Run "ip addr add ::1/128 dev lo" to add back lo's IPv6 address.
     Confirm checkipv6available() returns True.
  3. Start a web server taking the 8000 port.
     Confirm checkipv6available(8000) is still True.
