Duplicate strings.Count in path matcher

[hlidotbe]

Hi,

Unless I'm mistaken there's a redundant count in this check:

caddy/modules/caddyhttp/matchers.go

Lines 457 to 460 in f4840cf

	if strings.Count(matchPattern, "*") == 2 &&
	strings.HasPrefix(matchPattern, "*") &&
	strings.HasSuffix(matchPattern, "*") &&
	strings.Count(matchPattern, "*") == 2 {

if it's indeed a mistake I'll do a PR ASAP.

Oh the second one is there in case the first one fails.

...

j/k. Would happily accept a PR. Thanks!
