Userland: Fail Core::find_executable_in_path on empty inputs
Before this patch, `which ""` or `type ""` would say that the empty string is `/usr/local/bin/`. Convert callers to consistently call is_empty() on the returned string while we're at it, to support eventually removing the is_null() String state in the future.
