scripts: 'warn-about-old-distro' looks at the age of the running Guix.

This fixes a discrepancy that could be seen when running:

  sudo guix system …

where 'guix' would warn about the age of root's Guix, even though the
running Guix is the user's, not root's.

* guix/scripts.scm (warn-about-old-distro)[false-if-not-found]: Remove.
Obtain the profile date by calling 'current-profile-date' instead of
stat'ing "current-guix".
