[PATCH] README: note git-security@googlegroups.com

[Thomas Gummerer <t.gummerer@gmail.com>]

Add a mention of the security mailing list to the README.
2caa7b8d27 ("git manpage: note git-security@googlegroups.com",
2018-03-08) already added it to the man page, but I suspect that for
many developers, such as myself, the README would be the first place
to go looking for it.

Use the same wording as we already have on the git-scm.com website and
in the man page.

2caa7b8d27 ("git manpage: note git-security@googlegroups.com",
2018-03-08) also mentions SubmittingPatches, but I think people are
much more likely to submit a report of a security issue first, rather
than sending a patch, for which I think the README is more useful.
