hppa64: Fix fmt_f_default_field_width_3.f90 and fmt_g_default_field_width_3.f90

hppa64: Fix fmt_f_default_field_width_3.f90 and fmt_g_default_field_width_3.f90

The hppa*64*-*-hpux* target is not included in the set of fortran_real_16
targets because it doesn't have cosl.  However, these tests don't need
cosl, etc.
