attr: convert git_all_attrs() to use "struct attr_check"
This updates the other two ways the attribute check is done via an
array of "struct attr_check_item" elements. These two niches
appear only in "git check-attr".
* The caller does not know offhand what attributes it wants to ask
about and cannot use attr_check_initl() to prepare the
attr_check structure.
* The caller may not know what attributes it wants to ask at all,
and instead wants to learn everything that the given path has.
Such a caller can call attr_check_alloc() to allocate an empty
attr_check, and then call attr_check_append() to add attribute names
one by one.
