man/po: copy over login.defs.d/*.xml

[hallyn]

When doing update-po, we copy man/.xml into a tempdir, but some of those files reference login.defs.d/.xml, so copy over those as well.

@alejandro-colomar can you check whether this fixes 'make build' for you? It seemed to for me.

There's another problem with remove-potcdate.sed being created in man/ but needed under man/po/, but I'll handle that one next.

make build doesn't seem to exist. Did you mean make dist?

This patch fixes make dist for me, indeed. Thanks!
