    git-arc: add initial non-FreeBSD and `$HOME` install support
    
    Modify the existing code to permit setting a prefix via the `PREFIX`
    make variable, similar to what `--prefix` provides in autotools-based
    projects.
    
    Add the required compatibility glue in order to function with vanilla
    bmake, which enables installing the commands with Linux and macOS:
    - vanilla bmake requires `scripts.mk` to install `SCRIPTS`.
    - vanilla bmake does not tack `/man` on to the end of `MANDIR`, like
      with FreeBSD.
    
    Adjust the sysctl calls to instead look for `arc` in `$PATH` using
    `command -v` instead of hardcoding the path to the `arc` binary. This
    allows the command to invoke `phorge` as well as the legacy `arcanist`
    tool.
    
    While here, update the origin for `arcanist` as the former is the
    non-phorge fork is no longer supported (nor needed).
    
    NOTE:
    - regarding Linux support: this should now function out of the box with
      Linux as long as the host has access to an appropriate `arc` binary.
    - regarding macOS support: the arcanist/phorge packages do not yet
      exist in Homebrew or MacPorts, but are being added soon.
