Bug#843436: dpkg: FTBFS on !linux

[Samuel Thibault <sthibault@debian.org>]

Package: dpkg
Version: 1.18.11
Severity: important
User: debian-hurd@lists.debian.org
Usertags: hurd

Hello,

dpkg currently FTBFS on !linux:

../../scripts/t/Dpkg_Source_Package.t ...... ok
Dpkg_Dist_Files.t: error: badly formed line in files list file, line 1
# Looks like you planned 26 tests but ran 22.
# Looks like your test exited with 255 just after 22.
../../scripts/t/Dpkg_Dist_Files.t ..........
Dubious, test returned 255 (wstat 65280, 0xff00)
Failed 4/26 subtests

This is because when looking through files in the directory, load_dir
also looks at "." and "..", and it happens that on kfreebsd & hurd, one
can open a directory as a file (and we get the content of the directory
inode), so dpkg should explicitly test against directories, here is a
patch proposal.

This is quite bad since libdpkg-perl depends on dpkg:hurd-i386 (>=
1.18.11), so all packages using debhelper are currently non-buildable.
