Martin Storsjö f6bcd661f0 configure: Improve the check for schannel DTLS constants
This amends 307983b292 to fix
building with older versions of mingw-w64.

The previously checked constant, SP_PROT_DTLS1_X_CLIENT, was
added in mingw-w64 in df36f5deda23192d0ee99ffd661ea36df924e667
in 2020, and is included in released versions since v8.0.0.

The new checked constant SECPKG_ATTR_DTLS_MTU was added in
mingw-w64 in 0792283787cca8fc27dd38671107c791c87f4db3 in 2021,
and first appeared in mingw-w64 v9.0.0.

This fixes building with mingw-w64 v8, which is the version bundled
in Ubuntu 22.04.
