test-lib.sh: Add explicit license detail, with change from GPLv2 to GPLv2+.

Dear Junio,

this is a resend of relicensing patch for test suite library, which
was initially sent by Carl Worth. Since the time you sent me acks for
this patch collected by you, I collected 8 additional acks as is
documented at
https://git.wiki.kernel.org/index.php/Test-lib_reclicensing. There are
still three contributors missing: Bert Wesarg, Stephan Beyer and Bryan
Donlan. The contributions of first two are clearly not copyrightable.
I'm not sure about the copyrightability of Bryan Donlan's
contributions (git log -p --author='Bryan Donlan' t/test-lib.sh).

Carl told me that in your ack collection process you missed only three
acks. So I wonder whether you already did some analysis of which
contributions are copyrightable. If so, are the missing acks in the
list bellow?

Thanks
Michal

This file has had no explicit license information noted in it, but
has clearly been created and modified according to the terms of GPLv2
as with the rest of the git code base.

The purpose of relicensing is to allow other GPLv3+ projects (in
particular, the notmuch project: http://notmuchmail.org) to use this
same test-suite structure and to contribute changes back as well.
