box/socket.test is broken (again!)

also from Gentoo:

There is actually two different problems:
1.
-------------
exec admin "lua n, status, error_code, error_str = s:send(string.rep('=', 200000), 0.0000001)"
exec admin "lua type(n)"
exec admin "lua type(status)"
exec admin "lua type(error_code)"
exec admin "lua type(error_str)"
exec admin "lua status"
-------------
This test tries to send 200000 char within 0.0000001 sec time limit and check that 'timedout' error happens on the socket.

On modern Linux such small packets usually send without blocking on loopback interface.
=> Increase packet size
2.
-------------
exec admin "lua s:connect('::1', '30303')"
# connection refused
exec admin "lua s:error()"
-------------
This test checks IPv6 connection.
If IPv6 is disabled (rmmod ipv6 or net.ipv6.conf.all.disable_ipv6=1) then this test will fail.
=> Remove this check from socket.test
