Update git submodules

* Update system/core from branch 'main'
  to 53748d08e595066fc138b97051032799d7af7124
  - Merge "Prevent mte_upgrade_test from hanging if MTE is disabled" into main
  - Prevent mte_upgrade_test from hanging if MTE is disabled
    
    Turns out we didn't need the syscall because the kernel checks
    for async MTE fault on exit.
    
    Test: atest mte_upgrade_test with and without MTE
