pack-objects test: modernize style

Modernize the quoting and indentation style of two tests added in
8685da4 ("don't ever allow SHA1 collisions to exist by fetching a
pack", 2007-03-20), and of a subsequent one added in
4614043 ("index-pack: use streaming interface for collision test on
large blobs", 2012-05-24) which had copied the style of the first two.
