[yocto] meta-selinux: missing dependency on libxml2 in setools recipe

[Philip Tricca]

Mark,

I'm building meta-selinux against oe-core and found that the setools
recipe is missing a dependency on libxml2.  When building against Yocto
it looks like this dependency is satisfied by a recipe that's built
prior to setools.  Anyway, trivial patch below.

Thanks,
- Philip
