[KLIB] Keep "API for KLIB ABI" test data under "compiler/testData/klib/" dir

The test data is used both in ":kotlin-util-klib-abi" and
":native:native.tests" modules. It's better to keep it together with
the test data for other KLIB tests which are also used in more than one
module, i.e. in "compiler/testData/klib/" dir.
