EKS Launch Template now has multiple mentions of "NODE_TAINT"

[syvanen]

The awk on the quickinstall.sh line 161 fails because there's multiple lines with NODE_TAINTS=in the launch template now.

By adding -m1 limits the match to first hit making the awk replacement work again. Without this the daemon will fail to add/update the taint in main.py line 206 to fail as there are no taints defined on the node.
