[ruby/openssl] x509store: explicitly call rb_gc_mark() against Store/StoreContext

Browse source 
We store the reverse reference to the Ruby object in the OpenSSL
struct for use from OpenSSL callback functions. To prevent the Ruby
object from being relocated by GC.compact, we must "pin" it by calling
rb_gc_mark().
