*/*: Remove Uses=corosync

[fernape]

Summary

Unused in the tree.

Also I have doubts that this will work in the package clusters since it checks
for the installed version of net/corosync in order to stablish the _DEPENDS.

Test Plan

Apply patch, make describe from the ports tree root. No consumers.

I don't think that it's unused:

flo@p:~/dev/checkouts/portscommit/net/pacemaker2 % make -V USES
autoreconf:2.69 corosync cpe gmake gnome libtool ncurses pathfix pkgconfig python shebangfix gettext

It's in Makefile.common

You're absolute right. Thanks!
