Daan De Meyer 5c25f9dbc5 meson: Remove version_h dependency from jinja2_cmdline
version_h includes GIT_VERSION which only makes sense for C files
which aren't preprocessed by jinja2 so remove the argument.

The end result of this change is that the man pages are not recompiled
anymore every time GIT_VERSION changes.
