dgit: Abolish move_dsc_to_bpd

This subroutine only has one caller.  It also contains a bit of
duplication both within itself and compared to its caller - the calls
to mv and its error handling - which is annoying to remove as it is.

Instead, put its code into build_source, and break out a private
subroutine $mv for the rename.

No functional change other than to messages.
