MDEV-17958: Make innochecksum follow the build option

Innochecksum was being built as if WITH_INNODB_BUG_ENDIAN_CRC32:BOOL=OFF
had been specified.

Also, clean up tests:

innodb.innochecksum: Useless; superceded by innodb_zip.innochecksum.
innodb.innodb_zip_innochecksum: Remove; duplicated innodb_zip.innochecksum.
innodb.innodb_zip_innochecksum2: Remove; duplicated innodb_zip.innochecksum_2.
innodb.innodb_zip_innochecksum3: Remove; duplicated innodb_zip.innochecksum_3.

No test case was added. I tested manually by adding debug instrumentation
to both innochecksum and buf_page_is_checksum_valid_crc32() to make
innochecksum write the buggy crc32, and to get warnings for falling back
to the buggy checksum. Automating this would require that tests be
adjusted depending on the build options.
