In commit 0f7732d1
we introduced a innodb_checksum_algorithm=full_crc32 combination
to a number of encryption tests, and also fixed the code accordingly.

The default in MariaDB 10.5 is innodb_checksum_algorithm=full_crc32.
In a test merge to 10.5, the test encryption.innodb-redo-badkey failed
once due to a message that had been added in that commit.

Let us introduce a full_crc32 option to that test.
And let us use strict_crc32 and strict_full_crc32 instead of the
non-strict variants, for the previously augmented tests, to be in
line with the earlier tests encryption.corrupted_during_recovery and
encryption.innodb_encrypt_temporary_tables.
