Makefile.m32: stop forcing XP target with ipv6 enabled [ci skip]

Since this [1] commit in 2011, `_WIN32_WINNT` was set fixed to Windows
XP when the `-ipv6` option is selected. Maybe this was added to support
pre-XP Windows versions (?). These days libcurl builds fine for both XP
and post-XP versions with IPv6 support enabled. The relevance of pre-XP
version is also low by now. Other build methods also do not impose such
limitation for a similar configuration. So, drop this hard-wired
`_WIN32_WINNT` limit from `Makefile.m32`, thus building for the default
Windows version set by the compiler. This is Vista for recent MinGW
versions.

Old behaviour can be restored by setting this envvar:
export CURL_CFLAG_EXTRAS=-D_WIN32_WINNT=0x0501
