[bug#40274] [PATCH v7 1/2] services: Allow modprobe to use "/etc/modprobe.d".

[Brice Waegeneire <brice@waegenei.re>]

This is a temporary crutch allowing 'modprobe' to load it's
configuration from "/etc/modprobe.d". The definitive fix is contained in
<https://issues.guix.info/issue/40422> which need to go trough the
core-upates branch as it rebuild over 2200 packages.

* gnu/services.scm (%modprobe-wrapper): Set 'MODPROBE_OPTIONS'
environment variable.
