lxc: Disable use of unwanted libraries explicity

Otherwise one gets a failure if the libraries (e.g. Python
header file) exist in the build system.  Worse in some cases
is host headers being found if one doesn't specifically
disable a library search in autotools.  It is especially
important that Python is disabled by default.
