expl tests: Avoid test failure on NetBSD 10.0/i386

[Bruno Haible]

On NetBSD 10.0/i386, I see this test failure:

FAIL: test-expl
===============

../../gltests/test-exp.h:81: assertion 'err > - err_bound / TWO_MANT_DIG && err 
< err_bound / TWO_MANT_DIG' failed
FAIL test-expl (exit status: 134)

The expl() function is just more imprecise on this platform than elsewhere.
Here is a workaround:
