Check service exclude

[lgmu]

Extends check_service exclude parameter with wildcards, kept case-insensitive matching

e.g. check_service "exclude=Google*"

[lgmu]

exclude arg also exists in other checks but it doesn't really make sense to add the wildcard option there imo:

check_omd -> there are not that many services by default and usually shouldn't be excluded anyway
check_network -> currently case sensitive, I think here we could implement it, but then we should also make it case insensitive
check_drivesize -> for windows it doesn't make sense, for linux it could make sense in certain cases, but it's more complex because it currently already does stuff with trailing slashes or backslashes

the only thing that bothers me, is that this PR add the exact same test twice.
