nixos/version: add extraOSReleaseArgs and extraLSBReleaseArgs

Browse Source 
A free-form `attrsOf str` option that is merged with the /etc/os-release
builder, allowing downstreams to customise arbitrary os-release fields.
This is separate from the variant option, as using an attribute set
merge means one gets an infinte recursion when making extraOSReleaseArgs
a recursive set, and the variant attribute is useful to define elsewhere
or multiple times.

Ditto for /etc/lsb-release.
