man: tweak description of auto/noauto

I think the current behaviour is stupid: 'x-systemd.automount,noauto' should
mean that we create the units, but don't add .mount or .automount to any targets.
Instead, we completely ignore 'noauto'. But let's at least describe the
implementation.

Text suggested by dpartrid in the bug.

Fixes #21040.
