[cairo] [PATCH 2/3] build: Allow autogen-eration on systems without GTK-doc

[Andrea Canciani]

The autogen.sh script fails if it cannot run gtkdocize. The absence of
this command should cause cairo builds to fail, it should only prevent
the build of its documentation.

Fixes:
*** No GTK-Doc found, please install it ***

on systems without gtkdoc tools.
