xen: fix building with BASELIB=lib64

Many "real" (other then genericx86-64) x86-64 target machine configurations
set BASELIB to lib64. For example the intel-corei7-64 or the AMD
machines.

In such case packaging xen-python fails because items are
installed to /usr/lib/, but FILES_xen-python points to package
/usr/lib64/ items. Exposing the DISTUTILS variables from OE build makes
the python installation somewhat similar to what happens in the distutils
class and python items are installed to the /usr/lib64 as expected.

Another issue was that the xen-efi package was picking up too much stuff
from the /usr/lib64 path on such machines. Being more explicit at least
allows to package things correctly.

+Subject: [PATCH] python,pygrub: pass DISTUTILS env vars as setup.py args
+
+Allow to respect the target install dir (PYTHON_SITEPACKAGES_DIR)
+as well as other parameters set by the OpenEmbedded build system.
+This is especially useful when the target libdir is not the default one
+(/usr/lib), but for example /usr/lib64.
