Subject: Fix build on linux, enable build directory support

Specifically:

- Include stddef.h for missing ptrdiff_t
- Define PCAP_OPENFLAG_PROMISCUOUS if not using WinPcap because it seems to be
  a WinPcap extension
- Make use of CMAKE_CURRENT_{SOURCE,BINARY}_DIR to enable building under a
  directory other than root of the project
