Fix value EVP_PKEY_OP_TYPE_CRYPT as declared by OpenSSL

[squaresmini]

After upgrading OpenResty from 1.21.4.4 to 1.27.1.1, decryption of JWE fails with error "failed to decrypt key: invalid operation".

The error is raised by this line, and the err value comes from this line in OpenSSL project.

The reason should be the following:

• at this line the value of EVP_PKEY_OP_TYPE_CRYPT is 768 (1 << 8) | (1 << 9), while in Openssl is 1536 (1 << 9) | (1 << 10) as described here.
• Since EVP_PKEY_OP_DECRYPT equals (1 << 10), the bitwise comparison (ctx->operation & optype) returns 0, because optype = 768. However, this value has not been changed between OpenSSL versions.
• For reasons I don't fully understand, in Openssl 1.1.1n, this line is not triggered, wheras in Openssl 3.0.15 it is.

Changing EVP_PKEY_OP_TYPE_CRYPT should fix the problem.
