Add HAVE_BSD_UNISTD_H and HAVE_BSD_STDLIB_H definition to include 'bsd/unistd.h' and 'bsd/stdlib.h' headers.
This fixes gcc 6.1.1 and clang 3.8.0 implicit function declaration error (setproctitle and arc4random) on Linux system with 'libbsd' headers under 'bsd' include directory. Signed-off-by: Alif M.
