ipcpipeline: Rework compiler checks

Browse source 
`pipe()` isn't used since 15927b6511,
and `socketpair()` from `#include <sys/socket.h>` is used only in the
examples. In practice, you can use probably also use anything that
allows you to create fd pairs, such as named pipes or anonymous pipes.

We use the cross-platform GstPollFD API in the plugin.
