Small bug fix for ec2-scripts/ec2_fetchkey

[Bradley T. Hughes]

Howdy!

I noticed a small bug in ec2_fetchkey: it needs a '$' to expand ec2_fetchkey_user when grepping through /etc/passwd.

diff --git a/ec2_fetchkey b/ec2_fetchkey

 ec2_fetchkey_run()

 	# If the user does not exist, create it.
-	if ! grep -q "^{ec2_fetchkey_user}:" /etc/passwd; then
+	if ! grep -q "^${ec2_fetchkey_user}:" /etc/passwd; then
 		echo "Creating user ${ec2_fetchkey_user}"
 		pw useradd ${ec2_fetchkey_user} -m -G wheel
 	fi
