Fix `Integer.sqrt` to never exceed actual value
`Integer.sqrt` uses `sqrt(3)` from libm for small values.
This method must return a value less than or equal to the actual integer
square root, but libm's sqrt does not always guarantee that.
This change corrects that by decrementing the result if necessary.
Fixes [Bug #21217]
