fix: move paru repo config into moonarch.install to break bootstrap loop

The paru PKGBUILD repo config was only set up by post-install.sh and
transform.sh. If the config was missing on an existing system,
moonarch-git couldn't update — the fix required the package that
delivers the fix.

Now moonarch.install sets up the config on every install/upgrade.
post-install.sh keeps it for first-time bootstrap (before moonarch-git
exists). transform.sh no longer manages it.
