math: fix signed int left shift ub in sqrt

Both sqrt and sqrtf shifted the signed exponent as signed int to adjust the bit representation of the result. There are signed right shifts too in the code but those are implementation defined and are expected to compile to arithmetic shift on supported compilers and targets.
