activation: Operate on <user-account> and <user-group> records.
* gnu/system/accounts.scm (sexp->user-group, sexp->user-account): New procedures. * gnu/system/shadow.scm (account-activation): Call them in the arguments to 'activate-users+groups'. (account-shepherd-service): Likewise. * gnu/build/activation.scm (activate-users+groups): Expect a list of <user-account> and a list of <user-group>. Replace uses of 'match' on tuples with calls to record accessors. (activate-user-home): Likewise.
