Subject: activation: Set the right owner for home directories.

This fixes a regression introduced in
ae763b5b0b7d5e7316a3d0efe991fe8ab2261031 whereby home directories and
skeletons would be root-owned.

* gnu/build/activation.scm (copy-account-skeletons): Make 'directory' a
keyword parameter.  Add #:uid and #:gid and honor them.
[set-owner]: New procedure.
(activate-user-home): Add call to 'getpw' and 'chown'.  Pass UID and GID
to 'copy-account-skeletons'.
* gnu/tests/base.scm (run-basic-test)["skeletons in home directories"]:
Test file ownership under HOME.
