Refine some C in pcap-haiku.c. [skip ci]

Convert prepare_request() from bool to int and squelch the warnings:

./pcap-haiku.c:39:1: warning: no previous prototype for
  'prepare_request' [-Wmissing-prototypes]
./pcap-haiku.c: In function 'pcap_inject_haiku':
./pcap-haiku.c:110:47: warning: unused parameter 'buffer'
  [-Wunused-parameter]
./pcap-haiku.c:110:59: warning: unused parameter 'size'
  [-Wunused-parameter]
./pcap-haiku.c: In function 'get_if_flags':
./pcap-haiku.c:273:26: warning: unused parameter 'name'
  [-Wunused-parameter]
./pcap-haiku.c:273:58: warning: unused parameter 'errbuf'
  [-Wunused-parameter]

Remove pcap-haiku.cpp from the comment in build.sh.
