samples: net: Add relevant Posix headers for networking

jukkar · nashif · commit ac859d0e7736 · 2025-11-17T14:01:32.000-05:00
We need certain network related Posix header files so that the
network sample compiles ok. Previously the Posix symbols were
introduced by network stack automatically even if user had not
enabled Posix, but that is no longer the case.
