liblzma: Don't verify header CRC32s if building for fuzz testing. FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION is #defined when liblzma is being built for fuzz testing. Most fuzzed inputs would normally get rejected because of incorrect CRC32 and the actual header decoding code wouldn't get fuzzed. Disabling CRC32 checks avoids this problem. The fuzzer program must still use LZMA_IGNORE_CHECK flag to disable verification of integrity checks of uncompressed data.
