kernel: check package name before check manager signature (#3134)

If the package name of the manager is defined, check the package name
before checking the signature.

Fixed the issue where if a package name is defined, but the first
matching signature found by the kernel is not the manager, the real
manager cannot be crowned.
e.g. When Android Studio previews Compose, it installs a package with
the same signature as the manager on the device, such as
me.weishu.kernelsu.test
