Add Unlicense to coregrind/m_debuginfo/tinfl.c
The tinfl.c file comes from the public domain miniz project.
Upstream added an explicit Public Domain declaration using
the Unlicense. No other changes were made, so all our valgrind
specific changes still apply. This doesn't really change the
license as used for our derived version, which is distributed
under GPLv2+. But it adds some history and a legal statement
that is more clear than just saying "public domain".
This is the upstream commit:
