### What problem does this PR solve?
Problem Summary:
On glibc < 2.25, dynamic TLS can be allocated by libc and freed by jemalloc,
crashing during thread cleanup. Route `__libc_memalign` through the existing
jemalloc hook and add native allocator tests.
### Release note
Fix a BE crash during dynamic TLS cleanup on older glibc systems.
