dgit: Pass --no-renames to git diff-tree -z, avoiding potential trouble

Without this option, git-diff-tree might detect a rename (or possibly
even a copy).  If it does it prints a different output format with a
status of C or R *and a separate filename*.  The latter is an
additional nul-terminated record and would get dgit's interpreter of
the git diff-tree output out of step.

Actually understand foo,-security (!)

There does not in fact seem to have been any code which implements
this line from dgit(7):
    If a specified subsuite starts with - then mainsuite is prepended.
The code which canonicalises it back to the version with ",-" does
work, though.

Closes:#867189.
