meson: build .standalone versions of the report binaries

The goal is to be allow the use of those binaries on systemd with older
systemd. The report stuff is generally independent of the running systemd
version.

When built with -Dinstall-tests=true -Dstandalone-binaries=true
-Dbuildtype=release -Db_lto=true, gcc-16.1.1-2.fc44.x86_64, the sizes
are quite reasonable:
