[Inet] Fix setting for CLOEXEC flag at socket creation (#33164)

* [Inet] Fix setting for SOCK_CLOEXEC

The linux kernel allows to set the flag SOCK_CLOEXEC through the
parameter type[1].

The implementation sets the flag through the parameter protocol and
causes the call to socket()[2] to return -1 with EINVAL.

This fixes the behaviour by OR-ing the flag SOCK_CLOEXEC to type instead
of protocol.

* [Inet] Fix setting for O_CLOEXEC

The macro O_CLOEXEC is a filedescriptor flag.

The implemention sets the flag O_CLOEXEC as the parameter command given
to function fcntl[1] and causes the call to fcntl to return -1 with
EINVAL.

The flag O_CLOEXEC intends to be set using the command F_SETFD.

This fixes the behaviour by adding the missing command paramete F_SETFD
before the optional argument O_CLOEXEC.
