  Since revision 32, guix-data-service starts immediately but returns an HTTP
error code until initialization is complete. Adjust the test accordingly, and
remove the increased startup time limit.

* gnu/services/guix.scm (guix-data-service): Use default #:pid-file-timeout.
* gnu/tests/guix.scm (guix-data-service): Retry the http-get test several
times to give the service time to initialize.

Thanks Timotej, I've pushed this as
a15b769c2f81034884ef0ae7fa8c1cea8df45c56.

I've also updated the data service so that it responds with a 503 for
the healthcheck when starting up, rather than a 500, as that's a bit
nicer.
