[LTP] [PATCH] syscalls/chdir01: Add umask before mkdir

Hi Gongyi,

Thanks a lot for a giving example. I tested only 0066.

I'm sorry I accepted the Ziyao version as it had better description, reverted
back changes and will work on any mode in SAFE_MKDIR(). I put your Reported-by:
tag.

I'll also send one more fix for exfat.

Kind regards,
Petr
