test/fpcnv: skip comparing inexactly converted int
In C, if a floating point cannot be represented exactly as an integer, conversion from the former to the latter is implementation-defined. Therefore, it can be flaky to test this against QBE-defined behavior. This was discovered from (unsigned int) 4294967295.0f being an UB, because (uint64_t) 4294967295.0f is 4294967296 > UINT_MAX on amd64 when compiled by either gcc or clang.
