t5570 trap use in start/stop_git_daemon

["Randall S. Becker" <rsbecker@nexbridge.com>]

On the NonStop port, we found that “trap” was causing an issue with test
success for t5570. When start_git_daemon completes, the shell (ksh,bash) on
this platform is sending a signal 0 that is being caught and acted on by the
trap command within the start_git_daemon and stop_git_daemon functions. I am
taking this up with the operating system group, but in any case, it may be
appropriate to include a trap reset at the end of both functions, as below.
I verified this change on SUSE Linux.

diff --git a/t/lib-git-daemon.sh b/t/lib-git-daemon.sh
