This commit adds more benchmarks for inhibition rules where just the last rule in the benchmark inhibits the labels. Here is an example of these benchmarks:

BenchmarkMutes/10_inhibition_rules,_last_rule_matches-8        	 1094041	      1020 ns/op
BenchmarkMutes/100_inhibition_rules,_last_rule_matches-8       	  347079	      3306 ns/op
BenchmarkMutes/1000_inhibition_rules,_last_rule_matches-8      	   39068	     26769 ns/op
BenchmarkMutes/10000_inhibition_rules,_last_rule_matches-8     	    4387	    260687 ns/op

This didn't work when there was just 1 alert rule, 1ms was too short.
