s3: lib, s3: modules: Fix compilation on Solaris.
Based on work from YOUZHONG YANG <youzhong@gmail.com>.
Code needs fixing when HAVE_STRUCT_MSGHDR_MSG_CONTROL is
not defined. Also Solaris doesn't have msg_flags field
(which we set to zero anyway, so if we initialize
the entire struct to zero, we never need to refer to it).
