[FIR tests] do not distinguish builtins & library origins

fir which is retrieved by LL symbol providers based on stubs,
receives builtin origin when found in kotlin_builtins

pure compiler providers found the same fir declarations in stdlib
and thus receive Library origin

to avoid splitting the testdata, let's ignore the difference
