* systemd.pc: Keep support for rootprefix and root_prefix We dropped support for split-usr in https://github.com/systemd/systemd/commit/b0d3095fd6cc1791a38f57a1982116b4475244ba but kept the `rootprefix` variable in meson but ignore it to make sure we do not break downstream builds that depend on systemd. This is fine because we had logic in our meson.build that rootprefix and prefix need to be the same when split-usr=false. However we never had this logic in our systemd.pc.in file. This leads to a nasty breaking problem downstream. Many packages [0,1,2] (there might be more!) rely on overriding rootprefix or root_prefix when calling pkg-config to configure where to install systemd units. This is because before split-usr we installed units in rootprefix. Setting prefix on the pkg-config file didn't work. Even when split-usr=false people had to set rootprefix to install units in the right position. E.g. they have a line like: systemdunitdir = systemd.get_variable(pkgconfig: 'systemdsystemunitdir', pkgconfig_define: ['rootprefix', systemd_root_prefix]) With https://github.com/systemd/systemd/commit/b0d3095fd6cc1791a38f57a1982116b4475244ba landing This would mean all these downstream packages need to be patched to use `prefix` next to `rootprefix`. (Both need to be kept to keep backwards compat with using older versions of systemd). This puts a big burden on downstream packages. Instead we should not break the existing behaviour and keep the old behaviour of systemd.pc.in around. I've changed systemd.pc.in such that either setting prefix, rootprefix or root_prefix will all have the same effect. This way we do not break any downstream packages. - [0](https://github.com/fwupd/fwupd/blob/caa788b37ff34334d83debb047335fd12f3a7836/meson.build#L464) - [1](https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/blame/main/meson.build#L204) - [2](https://github.com/PipeWire/pipewire/blob/49cdb468c28ba366dbd08eef9cb6dbf2dea2a2e5/src/daemon/systemd/system/meson.build#L1)
