linux-user: fix getdents* syscalls
glibc's structs dirent and dirent64 is different from in-kernel dirent and dirent64. Kernel headers doesn't provide structs dirent(64) any more. So we should add it to qemu headers. To avoid conflict with glibc it called struct linux_dirent(64). Signed-off-by: Kirill A.
