Statically compiled encryption plugins do not work in mariadb-backup

In 10.9, when compiling hashicorp statically many InnoDB and mariabackup tests fails.

To repeat:
compile MariaDB with hashicorp statically and run:
mtr mariabackup.encrypted_page_corruption

Test fails with:
mysqltest: At line 76: command "rmdir" failed with error: 1 my_errno: 2 errno: 2
and var/log/mysqld.1.err contains a lot of failures like:

2022-06-13 12:14:35 0 [ERROR] InnoDB: The page [page id: space=5, page number=3] in file './test/t1.ibd' cannot be decrypted.
2022-06-13 12:14:35 0 [Note] InnoDB: However key management plugin or used key_version 1 is not found or used encryption algorithm or method does not match.
