[PATCH 2/3] inet_common: handle FEATURE_ETC_NETWORKS as a compile-time flag

[Johannes Schindelin]

This flag is used in #if ... #endif guards elsewhere and there is no
good reason to pretend that it is a runtime flag in just one case.

This probably was an oversight in a61cb92f2 (make /etc/network parsing
configurable. -200 bytes when off., 2007-06-19).

Besides, it fixes a compile problem on systems where the getnetbyaddr()
function is not available and the /etc/networks feature is disabled.
