Fix h_min after unintended change

SWINTEGERS was changed in 469bb84, and other critical usage of that
constant has to be adjusted accordingly.

There are still other places where SWINTEGERS are used, but as
long as tests pass they should be fine.

Also adjust the lower limit for h in test_slgof_hypo. If h can
become much lower than h_min, hypothesis shrinking in case of
errors becomes very slow.
