GUACAMOLE-2113: Improve warning when WoL is enabled but no MAC address is provided

[svkurupath-keeper]

Proposed fix for GUACAMOLE-2113

• Removed extra comma(,) in guac_user_log function calls so that the full message is logged.
• Added a comma for clarity with in the log message for RDP.

Results after local testing:

For VNC
guacd[273689]: WARNING: Wake on LAN was requested, but no MAC address was specified.  WoL will not be sent.

For SSH
guacd[299356]: WARNING: WoL was enabled, but no MAC address was provided.  WoL will not be sent.

For Telnet
guacd[298001]: WARNING: Wake on LAN was requested, but no MAC address was specified.  WoL will not be sent.

For RDP
guacd[299506]: WARNING: WoL requested, but no MAC address specified.  WoL will not be sent.

With respect to the changes themselves, LGTM.

A couple things need to be addressed before this is mergeable:

• As a minor fix/improvement that does not impact documentation, this should be against patch instead of main. (See the documentation covering our branching scheme.)

• The commit message needs to be formatted to match established formatting (JIRA issue followed by a colon, etc.).

Since each of the messages is being modified as a part of this, these changes could be a good opportunity to make these messages consistent (ie: WoL requested vs. WoL was enabled vs. Wake on LAN was requested vs. ...). I don't think that's deal-breaking, though.

Changed the target to apache:patch.
Changed the commit messages to reflect the established style for the project.
With the new changes, the same message will be used for logging each time when a WoL MAC Address is not specified.
