What this PR does / why we need it:

Normally, Falco would try to load any file or directory specified in rules_files or with the -r option. However, if you are trying to load a non-yaml file or a directory which contains both yaml and other types of files Falco would emit a fatal error on the first file that fails to load. Since it makes sense to put also other files in the rule directory (such as a README) this PR restricts the files that are considered to .yaml and .yml, ignoring the rest. Likewise, single files that do not end in .yml or .yaml will not be loaded.

Thanks to @tks98 for noticing the behavior and suggesting this improvement!
