pkg/tinydtls: bump version

[benpicco]

Contribution description

All our patches got merged, so we can drop them.
I did not find an upstream commit/PR for 0006-crypto-only-one-HMAC-context-is-required.patch, but it also no longer applies, so I dropped it. This patch was applied upstream too, it was just squashed - #17878 (comment)

Testing procedure

examples/gcoap_dtls still works

examples/gcoap_dtls still works

Confirmed. examples/dtls-echo runs into this assertion on native and iotlab-m3 at the client side: https://github.com/eclipse/tinydtls/blob/bda40789a7c280f248eeca6d09ddd624cdaf5dc8/session.c#L146 However, this is also the case on master, so that needs to be bisected (and is not a problem of this PR).

examples/dtls-sock and tests/pkg_tinydtls_sock_async work as expected.

Bisected using the following script (test_dtls.py deployed in RIOTBASE):

#! /usr/bin/env python3
import sys

from riotctrl.ctrl import RIOTCtrl

sys.path.append("dist/pythonlibs")
from riotctrl_shell.netif import IfconfigListParser, Ifconfig

if __name__ == "__main__":
    RIOTCtrl.MAKE_ARGS = ("-j",)
    ctrl0 = RIOTCtrl(application_directory="examples/dtls-echo", env={"WERROR": "0"})
    ctrl1 = RIOTCtrl(
        application_directory="examples/dtls-echo", env={"PORT": "tap1", "WERROR": "0"}
    )
    ctrl0.make_run(["distclean", "flash"])
    with ctrl0.run_term(reset=False), ctrl1.run_term(reset=False):
        ctrl0.term.logfile = sys.stdout
        ctrl1.term.logfile = sys.stdout
        shell0 = Ifconfig(ctrl0)
        shell1 = Ifconfig(ctrl1)
        netifs = IfconfigListParser().parse(shell1.ifconfig_list())
        server_addr = list(netifs.values())[0]["ipv6_addrs"][0]["addr"]
        res = shell1.cmd("dtlss start")
        assert res.strip() == "dtlss start"
        res = shell0.cmd(f"dtlsc {server_addr} hello")
        assert "Client: got DTLS Data App -- hello --" in res

git bisect good 9a2ccd51f45d78613432c724dbf3c
git bisect bad master
git bisect run python3 test_dtls.py

This found d424aae to introduce the regression. Seems like the functionality was not tested in #17765
