sha1dc: update to fix endianess issues on AIX/HP-UX Update our copy of sha1dc to the upstream commit 855827c (Detect endianess on HP-UX, 2019-05-09). Changes include fixes to endian detection on AIX and HP-UX systems as well as a define that allows us to force aligned access, which we're not using yet.
