Remove meaningless matchOverrides on static-method MethodMatchers

`matchOverrides=true` only changes how a `MethodMatcher` treats overrides of a
method on subtypes. Static methods cannot be overridden, so the flag is a no-op
on matchers that target them — it is misleading, and it can defeat precondition
optimizations that key on the declaring type.

Drop it from the static-method matchers in:
- MigrateCollections{Singleton,Unmodifiable}{Set,List,Map} (`Collections.*`, `Arrays.asList`)
- ChangeDefaultKeyStore (`KeyStore.getDefaultType`)
- FindLocaleDateTimeFormats (`DateFormat`/`DateTimeFormatter` factory methods)

Add a static-import regression test confirming the singleton recipe still fires
when the declaring type is never referenced directly.
