sys/cdefs.h: add definition of __attribute_alloc_size__
Commit cee0b058fa0b4501b289a2da365182d60314d746 ("add aligned_alloc
required for latest gcc libstdc++") added the prototype of
aligned_alloc() to <stdlib.h>. This prototype contains
'__attribute_alloc_size__ ((2))', but this is not defined anywhere in
uClibc-ng.
This commit addresses that by adding the relevant definition in
<sys/cdefs.h>, borrowed from glibc.
