[TEMP] modules/zstd/zstd_dec_test: Skip testing invalid ZSTD frames

Decodecorpus utility used for generating ZSTD frames for C++ tests of the
ZSTD Decoder generates invalid ZSTD frames when configured to generate
frames with RLE blocks for generator seeds: 41, 64, 92.

The frames generated with those seeds contain compressed blocks with RAW or RLE
literals instead of plain RLE blocks. Additionally, the frames cannot be
decoded correctly with the reference ZSTD library.

The above mentioned seeds will be excluded from the testing procedure.
