Dummy pkgbuild which depends on systemd-libs and provide libsystemd, which is already done by systemd-libs in [Core]
This is especially for Artix Linux, where 'libsystemd' is no longer provided by any package, but 'systemd-libs' is provided by a compatibility-package 'artix-archlinux-support' in [galaxy]. So in Artix Linux 'libsystemd-provides' translates the 'systemd-libs', provided by 'artix-archlinux-support', to 'libsystemd', needed by some AUR packages. The AUR is also used by other Arch-based distributions other than Arch (Artix even provides AUR-wrappers in it's own repos). So I ask that the package remains, for the Artix (and maybe Manjaro) folks.
