sqlfs_set_cipher_compatibility() doesn't exist in libsqlfs

[alinradut]

sqlfs_set_cipher_compatibility() doesn't exist in the latest libsqlfs (1.3.2) so trying to build IOCipher leads to the following error:

Implicit declaration of function 'sqlfs_set_cipher_compatibility' is invalid in C99

I wasn't able to find this function in any public repo.

Correction: I see this was added in the chatsecure fork: ChatSecure/libsqlfs@4456f8a
