services: cuirass: Allow for gexps in specifications.

Browse Source 
* gnu/services/cuirass.scm (<cuirass-configuration>)[specifications]:
Change default value to #~'().
(cuirass-shepherd-service): Remove conditional for "--specifications".
Use 'scheme-file' instead of 'plain-file'.  Change file name to
"cuirass-specs.scm".
* doc/guix.texi (Continuous Integration): Change the example to use a
gexp where #:file refers to a file within Cuirass.  Adjust
documentation.
