  BUG: fix denormal linspace test for longdouble

Linspace test was testing for case where simply dividing the range by
the number of samples generates 0, as the case for very small denormals.
The implementation generating the denormal only worked to exercise that
code for float64.  Make a small denormal that does exercise that case,
as least for longdouble, as well as float64.

Closes gh-8565.

  TST: add tests of nextafter around 0

Check that nextafter(0) gives number in range ]0 ... tiny[, and number
divided by 2 is 0 (denormal).
