Bug#901587: allegro4.4: please make the build reproducible

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that allegro4.4 could not be built reproducibly.

This is due to your changes in:

  https://salsa.debian.org/games-team/allegro4.4/commit/c4094628fea5c677105522ec4c805b452cb43229

The problem being that your date resolution is too coarse so it varies
the timezone. I suggest replacing all of that boilerlate with:

  include /usr/share/dpkg/pkg-info.mk

 And then change the tar call to use:

   --mtime="$(SOURCE_DATE_EPOCH)"

... which is also far cleaner.
