Fix random coverage in std.algorithm.sorting

[wilzbach]

The random coverage error appearing in #5570, is, as usual, our fault.

However, this one can be fixed easily - we just need to use the fixed seeds for the random number generator ;-)

Obvious bugfix aside, did you check that the e == 25 line is covered by one of the fixed seeds? If it's not, then the random coverage changes will likely not be fixed.

Yep, that's how I noticed the bug ;-)
