Subject: host-dummy-install-info: new package

For each package with info pages, install-info creates
'<pkgdir>/<prefix>/share/info/dir'. If packages are built in parallel, then
multiple install.post stages may try to create this file in <sysroot> at
exactly the same time and fail.

This fake install-info does nothing, so to avoid this race condition.
