services: lightdm: Do not use GOOPS.

Browse source 
There's an unwritten policy to not use GOOPS in Guix.

* gnu/services/lightdm.scm (strip-class-name-brackets): Rename to...
(strip-record-type-name-brackets): ... this.
(config->name): Adjust accordingly and use 'record-type-name' instead of
'class-name'.
(list-of-greeter-configurations?): Likewise.
