renamed some filenames to not end with a period

Windows does not allow such filenames, which prevented cloning git-annex
on windows.

+Unfortunately the added nix section broke the i386-ancient build,
+which uses stack 1.0.4. That version of stack complains:
+
+Executable named nix-shell not found on path: ["/usr/local/sbin","/usr/local/bin","/sbin","/bin","/usr/sbin","/usr/bin"]
+
+So, I've reverted the addition of that section.
