Libxml2 when not available from OS

[ocaisa]

This only worked initially because setup.py found the libxml headers from the system. When these are not available the installation fails.

Also need to explicitly tell the configure not to build the python bindings itself (otherwise it will try to install them as an extension to the python it finds and you might not have permission there...and it's also not what you want).

jenkins: ok to test

[JensTimmerman]

Looks fine to me, I have no idea why this worked for me then, since I don't have permission to install things in the system python.

I ran into a problem because someone else (actually me by another name) had installed the Python dep. It tried to install the modules there by default, I only got around it by explicitly switching the bindings off for the configure.

@ocaisa: should the sanity check be enhanced to catch this problem, i.e. to check that the Python bindings are available from the libxml2 install prefix?

[ocaisa]

Done, also checked that the expected happens when someone manually adds --with-python in the easyconfig - --without-python added in the block takes precedence (as expected)

Thoroughly tested with existing libxml2 easyconfigs, works like a charm, thanks @ocaisa!
