sys_socket: fix declarations test

[Bruno Haible]

On Solaris 11 2010-11, I'm seeing these messages from 'configure':

checking whether socket is declared without a macro... no
checking whether connect is declared without a macro... no
checking whether accept is declared without a macro... no
checking whether bind is declared without a macro... no
checking whether getpeername is declared without a macro... no
checking whether getsockname is declared without a macro... no
checking whether getsockopt is declared without a macro... no
checking whether listen is declared without a macro... no
checking whether recv is declared without a macro... no
checking whether send is declared without a macro... no
checking whether recvfrom is declared without a macro... no
checking whether sendto is declared without a macro... no
checking whether setsockopt is declared without a macro... no
checking whether shutdown is declared without a macro... no

The reason is a mistake in m4/sys_socket_h.m4. This should fix it.
