sqlfs_set_cipher_compatibility() doesn't exist in libsqlfs

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: https://github.com/ChatSecure/libsqlfs/commit/4456f8a83c7af7dc6b8cf6456dae94fe7979c24c
