build: Add conditional compilation

Two conditionals are introduced in this commit:
- if <ifaddrs.h> is not available, NetworkInterface helper will always return
  an empty set of interfaces
- If dropping/elevating effective user/group is not supported, an error
  will be thrown if used (e.g., if general.user or general.group is
  configured)

Both conditionals are necessary on Android platform.
