[PATCH libXi] config: replace custom code with reusable macro XORG_WITH_XMLTO

[Gaetan Nadon]

XORG_WITH_XMLTO provides additional functions like a configure
option which allow platform builders to control the usage of
the xmlto program.

This is a requirement from platforms that do not have such doc tool.
