CMake: fix broken daemonization and syslog functionality
While CMake is not the official way to build OpenVPN on Linux,
it still make sense to support it. Turns out that
HAVE_SETSID, HAVE_OPENLOG and HAVE_SYSLOG
were not set by CMake configure, and --daemon and syslog
functionality was broken.
While on it, fix compiler error on unused return value of chdir().
