sha1dc: update from upstream

Update sha1dc from the latest version by the upstream maintainer[1]. See 2db87328ef ("Merge branch 'ab/sha1dc'", 2017-07-10) for the last update. This fixes an issue where AIX was wrongly detected as a Little-endian instead of a Big-endian system. See [2][3][4]. 1. https://github.com/cr-marcstevens/sha1collisiondetection/commit/232357eb2ea0397388254a4b188333a227bf5b10 2. https://github.com/cr-marcstevens/sha1collisiondetection/pull/45 3. https://github.com/cr-marcstevens/sha1collisiondetection/pull/42 4. https://public-inbox.org/git/20180729200623.GF945730@genre.crustytoothpaste.net/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
