services: Rename field in greetd-terminal-configuration record.

This was erroneously renamed during the review of commit
ee0d1b144c ("services: greetd: Improve greeter configurations.").  The field
*adds* to the intrinsic requirements of the service, so the 'extra-' prefixes
communicates this better.

* gnu/services/base.scm (<greetd-terminal-configuration>): Rename
shepherd-requirement field to extra-shepherd-requirement.
* doc/guix.texi (Base Services): Adjust doc accordingly.
