Use FLEX_ALLOC_STR() to allocate the `struct untracked_cache_dir`
for the root directory.  Get rid of unsafe code that might fail to
initialize the `name` field (if FLEX_ARRAY is not 1).  This will
make it clear that we intend to have a structure with an empty
string following it.

I had to read this patch message a few times over to make sure that I
wasn't missing something in the patch itself, but it looks all good to
me.
