limits-util: use MUL_SAFE for physical memory calculation

Coverity flags (uint64_t)sc * (uint64_t)ps as a potential overflow.
Use MUL_SAFE which Coverity understands via __builtin_mul_overflow.
Physical page count times page size cannot realistically overflow
uint64_t, but this makes it provable to static analyzers.
