Fill the process environment with an BAREOS_CFGDIR

When we parse a configfile we push the directory we found it in into the
process environment as BAREOS_CFGDIR so you can use that same directory
as %BAREOS_CFGDIR% on windows and $BAREOS_CFGDIR on UNIX when
referencing an other configfile in that same directory.
