Tom Cherry b5ac55a444 asan_extract: add system_file_type to asan_extract_exec
This is on the system partition and thus must be system_file_type:

neverallow check failed at out/target/product/vsoc_x86/obj_asan/ETC/userdebug_plat_sepolicy.cil_intermediates/userdebug_plat_sepolicy.cil.tmp:7703 from system/sepolicy/public/domain.te:950
  (neverallow coredomain base_typeattr_272 (file (entrypoint)))
      <root>
          allow at out/target/product/vsoc_x86/obj_asan/ETC/userdebug_plat_sepolicy.cil_intermediates/userdebug_plat_sepolicy.cil.tmp:16250
	        (allow asan_extract asan_extract_exec (file (read getattr map execute open entrypoint)))

Bug: 155905226
Test: build without above neverallow error
