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.
