[XEN PATCH v3 4/4] README: remove old note about the build system's python expectation

[Javi Merino <javi.merino@xxxxxxxxx>]

5852ca485263 (build: fix tools/configure in case only python3 exists,
2019-12-11) changed the configure script to test for the availability
of python3, python and python2 in that order.  It sets PYTHON to the
first one found in path.  You don't need to have a symlink to python.

Remove the outdated note from the README.
