Siddhesh Poyarekar c9188d3337 memalign: reinstate alignment overflow check (CVE-2026-0861) 
The change to cap valid sizes to PTRDIFF_MAX inadvertently dropped the
overflow check for alignment in memalign functions, _mid_memalign and
_int_memalign.  Reinstate the overflow check in _int_memalign, aligned
with the PTRDIFF_MAX change since that is directly responsible for the
CVE.  The missing _mid_memalign check is not relevant (and does not have
a security impact) and may need a different approach to fully resolve,
so it has been omitted.
