Subject: [PATCH] units: avoid redundant VT clearing by agetty

TTYVTDisallocate=yes already clears the VT. agetty does not need to do
it again. Run it with --noclear.

Felix Miata found the double clearing confusing in this bugreport:
https://bugzilla.redhat.com/show_bug.cgi?id=828007
Add a comment explaining what clears the VT.
(cherry picked from commit 3305d6806d428010b1cd2abd716aa1bb7f81311f)
