Make first block of allocator_avl 64bit fit

Browse Source 
The first metadata-block, which is inherent part of the allocator object
itself has a fixed size which isn't suitable enough for some 64bit platforms
(e.g. core's RAM-allocator on a 64bit platform with lots of different regions).
This commit let the block size be address-width aware.
