[LTP] [PATCH] syscalls/statx*: Fix compiler errors on old distros

[Xiao Yang]

With glibc-2.5 on RHEL5, compilation failed because of undefined
AT_FDCWD, O_DIRECTORY or WEXITSTATUS().

1) Fix undefined AT_FDCWD and O_DIRECTORY by defining _GNU_SOURCE.
2) Fix undefined WEXITSTATUS() by including <sys/wait.h>.
