Subject: [PATCH] sys/ioctl: extend the IOCTL defintion that compatible with
 linux kernel

Add the generic _IO() macro and aliases for FS_IOC_GETFLAGS and FS_IOC_SETFLAGS,
aligning the ioctl.h definitions with the Linux kernel API to improve source
compatibility when porting LTP linux kernel testcase code to NuttX
