Subject: [PATCH] build: only demand an xsltproc program when it is used

It's intrinsically used when building manpages, and also part of the
introspection-specific parts of the documentation build. There's no
particular guarantee either of those will actually be invoked during a
build, so don't unconditionally look it up.

This allows building with one fewer dependency in many cases.
