Add a valgrind suppressions file set to suppress the zlib error which otherwise

pops up immediately on the fuzzbot. Hopefully there won't be too many more of
these.

+# This file lists suppressions to hide valgrind errors in libraries we don't
+# control. Be careful adding to it, since overly-broad suppressions may hide
+# real errors in Wireshark!
+#
+# This is primarily targeted towards the set of libraries on the fuzz-bot (which
+# runs a valgrind step) but other entries are welcome as long as they are
+# sufficiently commented.

+# Zlib 1.2.3.4 on the buildbot hits an uninitialized jump on the first call to
+# inflateReset2. According to the Zlib changelog this was fixed in 1.2.3.7.
