lxcfs: move recipe from meta-overc to here

This recipe was originally written and included in meta-overc as it
was used by the overc framework so we implemented it there to sort out
the kinks. Since this package is not specific to the OverC framework
and people may be interested in including it in their images without
having any interest in the OverC framework we are moving this recipe
here, alongside lxc and other container related recipes.

+Subject: [PATCH] systemd: allow for distinct build directory
+
+The Makefile.am is currently written in a way that doesn't allow for a
+distinct build directory. As such we get the error:
+
+    install: cannot stat 'lxcfs.service': No such file or directory
+
+Make use of $(srcdir) to correct this.
