I'm reluctant to take a patch that has been rejected upstream,
especially for a core package such as libxml2.  Porting can be
time-consuming which delays security updates, and we'll have situations
where something "works on Guix" but not elsewhere (or vice versa).

Will adding it as a separate package be sufficient?  We could call it
"xmllint-xpath0" or similar and make it clear that it's just libxml2
with a patched xmllint in the description.

Thoughts?
