xx-info env: remove cond to print XX_TRIPLE

[crazy-max]

XX_TRIPLE is not returned for windows platform with xx-info env and therefore CC and CXX vars are not exported with xx-go. Related to moby/moby#43529 (review).

I don't really understand why there is a os filter at all in here. Maybe it is a historic relic from the time only Linux was supported.

Looks like this cond has been added here: 1b606ea#diff-2e3d3a4d78f2753f9464b79e8ac808928efdaeb5e0976104bad6f360448ad856R304-R307

Maybe it was to handle specific suffixes:

xx/base/xx-apt

Lines 160 to 167 in c6d3201

	if [ "$XX_OS" = "windows" ]; then
	case "$XX_ARCH" in
	amd64) suffix="mingw-w64-x86-64" ;;
	386) suffix="mingw-w64-i686" ;;
	arm64) suffix="mingw-w64-aarch64" ;;
	arm) suffix="mingw-w64-arm" ;;
	esac
	fi

...for mingw packages like the apt one?:

xx/base/xx-apt

Lines 193 to 208 in c6d3201

	for p in ${packages2}; do
	n=
	if [ -n "$nocross" ]; then
	n=${p}
	elif checkpkg "${p}-${suffix}" >/dev/null 2>/dev/null; then
	n="${p}-${suffix}"
	elif [ "${XX_OS}" = "linux" ] && [ -n "${XX_APT_PREFER_CROSS}" ] && checkpkg "${p}-${XX_PKG_ARCH}-cross" >/dev/null 2>/dev/null; then
	n="${p}-${XX_PKG_ARCH}-cross"
	elif [ "${XX_OS}" = "linux" ]; then
	n="${p}:${XX_PKG_ARCH}"
	else
	continue
	fi
	empty=
	set -- "$@" "$n"
	done

PKG_ARCH should probably remain under condition as we only support linux package managers.

Yes indeed we don't support Cygwin pkgs
