UnixPkg: Fix build for Linux

UnixPkg/UnixSnpDxe is currently BSD/OS X specific.
Therefore we only build it if "-D NETWORK_SUPPORT"
is used on the build command line.

UnixPkg/build.sh and UnixPkg/build64.sh are updated to
automatically define NETWORK_SUPPORT if building on OS X.

<net/if_dl.h> and <net/bpf.h> are also only included in
UnixPkg/Include/Common/UnixInclude.h if __APPLE__ is defined.
