TAKE - fix filldir calls in test8

[Steve Lord <lord@xxxxxxx>]

This should fix some problems with removing directories, if glibc
is using getdents64 to read a directory we were failing to fill
in the filetype at all. This resulted in user space assuming that
a directory was not a directory and using unlink on it.
