xlat: use unsgined type for mount_flags fallback values

Reported by cppcheck:

    strace/xlat/mount_flags.h:256: error[shiftTooManyBitsSigned]:
    Shifting signed 32-bit value by 31 bits is undefined behaviour
    #  254|    XLAT(MS_BORN),
    #  255|    XLAT(MS_ACTIVE),
    #  256|->  XLAT(MS_NOUSER),
    #  257|    XLAT_END
    #  258|   };

* xlat/mount_flags.in: Use 1U instead of 1 as a bit shifting operand.
