[PATCH 2/5] liburing.h: Populate SQE for {s,g} etsockopt

[Breno Leitao <leitao@debian.org>]

The current io_uring_prep_cmd_sock() liburing function is not populating
the SQE will all the fields because the kernel implementation was not
ready.

With the integration of the kernel part[1], populate the SQE with the
missing fields (optlen, optval, level and optname). This enables
the usage of this function to prepare commands that executes setsockopt
and getsockopt operations.
