Update databases/mongo-c-driver to 1.3.5.

1.3.5
This release fixes a crash in mongoc_cleanup when an allocator
had been set with bson_mem_set_vtable, and introduces
a configure option MONGOC_NO_AUTOMATIC_GLOBALS which prevents
code built with GCC from automatically calling mongoc_init and
mongoc_cleanup when your code does not.

1.3.4
This release fixes a security vulnerability: when a mongoc_client_t
uses SSL and is disconnected, it failed to re-verify the server
certificate after reconnecting. This flaw affects
single clients, not pooled ones.
