xen, xen-tools: update recipes for python3

Adds patches for packaged scripts to enable deployment with python3
where they have been ported to python 3 upstream.

setuptools3 inherits distutils3 which modifies ${B}, so cd ${S} is
needed in the do_configure, do_compile and do_install steps.

Remove python 2 dependency from the Xen recipes by adding a new
separate recipe, xen-python2, for packaging the remaining optional
scripts which are yet to be ported to python 3. Package naming in
the separate recipe is chosen to support transition back into the
xen-tools recipe if the scripts are ported later.

Use RSUGGESTS to support inclusion of the xen-python2 scripts in
images that include python 2.

Drop the remus package python dependency since the script was removed
in 2014: commit 5b66f84e37a45038f9e5dae7a5768a5525d1e6ba

Add python3 RDEPENDS needed to run xenmon.
