MAINT: core: Remove duplicated inner loop ee->e from log, exp, sin, cos, sqrt.
MAINT: core: Remove duplicated inner loop ee->e from log, exp, sin, cos, sqrt.

The ufuncs log, exp, sin, cos and sqrt had two occurrences of the signature
ee->e, with the corresponding generic loop function PyUFunc_e_e_As_f_f.
This change removes the generation of the duplicated function from the
array of inner loops for these ufuncs.  The *first* entry of ee->e is
kept; tests fail if the first one is removed instead of the second.
