services: Move configuration functions that shouldn't be factorized.
* gnu/services/configuration.scm (serialize-field, serialize-string) (serialize-space-separated-string-list, space-separated-string-list?) (serialize-file-name, file-name?, serialize-boolean): Move these functions... * gnu/services/cups.scm: ...to this file. * gnu/services/kerberos.scm: ...to this file. Configuration syntaxes are very specific to services. Some services may have the same configuration syntax, but none of them is common enough to be abstracted in configuration.scm.
