内核defconfig修复：禁用QEMU不支持的安全特性和MTE

qemu-arm-linux_standard_defconfig修改：
- 禁用：CONFIG_KSM、CONFIG_SECURITY、CONFIG_SECURITY_SELINUX、CONFIG_FS_VERITY、CONFIG_SECURITY_CODE_SIGN、CONFIG_SECURITY_XPM、CONFIG_ARM64_MTE
- 启用：CONFIG_SECURITYFS、CONFIG_HAVE_HARDENED_USERCOPY_ALLOCATOR、CONFIG_DEFAULT_SECURITY_DAC
QEMU虚拟平台不需要SELinux、代码签名、XPM等安全特性，禁用后避免内核编译依赖缺失；MTE因QEMU不支持需禁用；DEFAULT_SECURITY_DAC作为禁用SELinux后的替代安全模型
