libgo patch committed: Use DialTimeout in self-connect test

[Ian Lance Taylor]

This patch from Uros Bizjak changes TestSelfConnect to use DialTimeout,
to avoid a problem where some operating systems take a long time to fail
a connection to localhost.  This patch adds a timeout to make the
connection fail quickly.  This is PR 59506.  Ran Go testsuite on
x86_64-unknown-linux-gnu.  Committed to mainline.
