xcb: don't build-depend on python-native

xcb-proto had a dependency on python-native as it builds and installs a Python
module, but xcb-proto is very low in the build to force a dependency on
python-native.

As it turns out libxcb simply asks pkg-config for the full path to the module
xcb-proto installed and uses it directly so there is no need to build
python-native.  Instead replace AM_PATH_PYTHON with two explicit variable
definitions (need to set PYTHON for automake's install logic).

Also remove the dependency on xcb-proto-native as libxcb uses the data files and
tooling from the target sysroot, and patching it to use the native sysroot adds
complication for no good reason.

+Upstream uses AM_PATH_PYTHON to find a python binary and ask it where to install
+libraries.  This means we either need to depend on python-native (large build
+dependency, early in the build) or use the host python (pythondir reflects the
+host and not the target, breaks builds).
+
+The third option is to just hardcode the path where the module goes, as most
+callers of the code use pkg-config to find where it was installed anyway.
