test: Drop --no-rebuild from meson test invocations

With meson 1.7.0, meson won't rebuild the world anymore when running
meson test so since meson 1.7.0 is in tumbleweed, debian testing, fedora
rawhide and Arch Linux, drop --no-rebuild from the docs since all the default
tools trees built by mkosi in the systemd repo will have meson 1.7.0 or newer
installed.

We keep --no-rebuild in CI because in CI we run with the same tools tree
distribution as the target distribution we're building and in those it's not
guaranteed for meson 1.7.0 to be available yet.

The advantage of dropping --no-rebuild is that meson will now reconfigure itself
if needed, which is required if we change or move around meson files, as otherwise
meson tends to explode spectacularly in hard to debug ways.
