man/po/Makefile.in: switch from xml2po to itstool

xml2po is deprecated.  We've previously replaced xml2po with
itstool in man/generate_translations.mak, but there was still
an instance of it that only is exercised for 'make dist'.
Update that one.  Now 'make dist' succeeds on a ubuntu focal
or newer host where xml2po is not available.
