mem-pool: use st_add() in mem_pool_strvfmt()

If len is INT_MAX in mem_pool_strvfmt(), then len + 1 overflows.
Casting it to size_t would prevent that.  Use st_add() to go a step
further and make the addition *obviously* safe.  The compiler can
optimize the check away on platforms where SIZE_MAX > INT_MAX, i.e.
basically everywhere.
