dgit: Don't rebind date

This generates a warning
  "my" variable $date masks earlier declaration in same scope at /home/ian/things/Dgit/dgit/dgit line 2190.

Possibly we should disable this warning, but it might be saving us
from other kinds of bugs.  (In Rust where I have gained this rebinding
habit, the type system will generally spot mistakes.)

Closes: #1055528
