This is a follow-up of #1340.

Previously changed to use LoadPackagedLibrary for better Xbox compatibility but this is not necessary for system libs (only for app's packaged libs). In fact, it is counterproductive to use it for OS libraries.

Since here only is used for kernelbase, ntdll, kernel32, bcrypt and psapi (all system libs) is better remove the use of LoadPackagedLibrary.

Is confirmed is working in Python build for Xbox (Python code includes mimalloc).

This comment #1340 (comment) also supports the same thing.

Sorry, something went wrong.

Uh oh!
