Bug description:
  Please backport upstream dpkg patch "libdpkg: Only preallocate disk
  size for files bigger than 16 KiB" to xenial, yakkety, and zesty
  versions of dpkg.

  dpkg 1.17.11 commit "dpkg: Try to preallocate the disk size for
  extracted files" causes installs of packages with many small files to
  be slow.
  https://anonscm.debian.org/git/dpkg/dpkg.git/commit/?id=87b0b20b86407baf1deb4e91b3fd839e01228ac8

  This was fixed in dpkg 1.18.15 with "libdpkg: Only preallocate disk
  size for files bigger than 16 KiB".
  https://anonscm.debian.org/git/dpkg/dpkg.git/commit/?id=a971ad91437af8880cad4703695dcf12ee45959b

  trusty dpkg is based off 1.17.5 and is not affected. xenial dpkg based
  off 1.18.4, yakkety dpkg based off 1.18.10, and zesty dpkg based off
  1.18.10 need the fix.
