osx: add an homebrew formula

This formula is currently incorrect because of the bad MD5 sum. We
will correct it at the first release supporting Mac OS X.

-Also create `/var/run/lldpd`:
+Alternatively, you can use a convenient brew formula:
 
-    mkdir -p /var/run/lldpd/etc
-    cp /etc/localtime /var/run/lldpd/etc/.

+
+This formula includes the ability to interface properly with launchd
+to start `lldpd` at boot.
