services: ntp: Fix a crash when using legacy configuration.
Fixes issue #37504 (see: https://bugs.gnu.org/37504). The bug was caused by the fact that destructuring an <ntp-configuration> record using match would bind the 'servers' field without using the compatibility accessor. * gnu/services/networking.scm (ntp-shepherd-service): Replace `match-lambda' by distinct `lambda' and `match' calls, so that the 'servers' field can be generated by applying the `ntp-configuration-servers' procedure to the configuration object.
