lxc: Fix build error with glibc 2.26

This issue doesn't necessarily have to do with glibc 2.26 and it could have been fixed if we'd replace -Werror with -Wall. The error in question was: storage/overlay.c:808:13: error: 'dirlen' may be used uninitialized in this function [-Werror=maybe-uninitialized] After looking at the code in overlay.c it indeed might use dirlen unitialized. Unrelated to the glibc upgrade which brought the problem to the surface, this also has been fixed upstream at lxc/lxc@180c477a326ce85632249ff169. The reason however, that led to the upstream fix was a segfault which has been reported at lxc/lxc#1802. Signed-off-by: aszlig <aszlig@nix.build> Cc: @wkennington, @globin, @fpletz
