logging: Add .log to samples and update asterisk.logrotate.

Added .log extension to the sample logs in logger.conf.sample so that
they will be able to be opened in the browser when attached to JIRA
tickets. Because of this, asterisk.logrotate has also been updated to
look for .log extensions instead of no extension for log files such as
full and messages.

+The sample logger files have been changed to have .log as their file
+extension. This was done so that when attached to issues on the issue
+tracker, they are able to be opened in the browser for convenience.
+Because of this, the asterisk.logrotate script has been updated to look
+for .log extensions instead of no extension for files such as full
