ldbl-128ibm: simplify iscanonical.h

The test for enabling _Float128 or IEEE 128 long double can be
greatly simplified knowing that there is no ibm128, thus we require
no special cases, and everything is canonical.

This reverts the changes to ldbl-128ibm iscanonical.h from commit
8dbfea3a2094798a52cebddde01d255483f49665 and extends the check
for __NO_LONG_DOUBLE_MATH to include a check for float128 redirects
to long double.
