Replace inplace macro with upstream macro
    
    Currently, the inplace macro only influences whether we use
    tools/meson-vcs-tag.sh to figure out the version instead of using
    the predefined one. But doing an inplace build shouldn't really
    affect the version, since it's possible to do an inplace builds that's
    not a git main upstream build, so the two concepts are disjoint.
    
    Instead, let's replace the "inplace" macro with an "upstream" macro
    to indicate that we're building from systemd git upstream. Aside from
    influencing the version, this also disables various patches and adds
    a libarchive dependency that was added upstream recently but isn't in
    an official release yet.
