Updates to rpm/barnyard* files to adhere to recent release

* FIX: SysVinit script of barnyard2, rpm/barnyard2 uses capitalized
form of cli argument(-L). This leads to failure of init script during
execution. Updated it to use correct option, -l.

* FIX: barnyard2 config file, rpm/barnyard2.config, has configuration file location set
to /etc/snort/barnyard.conf. This leads to init script crash. This
commit updates it to /etc/snort/barnyard2.conf
