Subject: [PATCH] uefi-services: Change panic handler log message.

The panic handler now displays its log message using `println!` instead
of `error!`. The message prefix is altered from [ERROR] to [PANIC].
The extraneous filename and line number printed by `error!` are also
removed from the log message.
