[LTP] [PATCH] getdents: account for d_name size in tst_dirp_size

[Andreas Schwab <schwab@suse.de>]

The linux_dirent and linux_dirent64 structs do not contain space for the
d_name member.  Add NAME_MAX to the size in tst_dirp_size so that the
getdents syscalls do not spuriously fail with EINVAL instead of EFAULT.
