mercurial: Explicitly disable largefiles extension when no config value is present for it.

Recent mercurial versions enable the largefiles extension in the hgrc file when
cloning from a repo that uses largefiles. This may lead to undesired behaviour.

By explicitly disabling it in the baseui object we override the setting in the hgrc file.
