The ISO C function time() should not depend on POSIX and this was corrected recently via the common libc time() implementation. Remove this dependency from the network subsystem where it has been unduly needed for some time. Similarly, XSI_SINGLE_PROCESS was a dependency for time() via picolibc, because the time() implementation in picolibc relies on the POSIX gettimeofday() call. However, since Zephyr's common libc time() implementation no longer depends on that, it can be removed as a dependency in the network subsystem as well.
