Remove incorrect alloc_size attribute from pvalloc [BZ #25401]
pvalloc is guarantueed to round up the allocation size to the page
size, so applications can assume that the memory region is larger
than the passed-in argument. The alloc_size attribute cannot express
that.
The test case is based on a suggestion from Jakub Jelinek.
This fixes commit 9bf8e29ca136094f73f69f725f15c51facc97206 ("malloc:
make malloc fail with requests larger than PTRDIFF_MAX (BZ#23741)").
