Fixes &lt;https://bugs.gnu.org/27551&gt;.
Reported by Leo Famulari &lt;leo@famulari.name&gt;.

This reinstates the following commits:

  e3ddb1e83 * gnu: guile-cairo: Switch to Guile 2.2.
  ae5c6ef39 * gnu: guile-gnome: Update to 2.16.5.
  0fd8013fc * gnu: guile-rsvg: Update to commit 05c6a2fd.
  66b9183c4 * gnu: guile-lib: Switch to Guile 2.2.

and adds the following changes:

* gnu/bootloader/grub.scm (svg-&gt;png): Add 'package-&gt;derivation' call for
GUILE-2.2.  Pass #:guile-for-build to 'gexp-&gt;derivation'.
* gnu/build/svg.scm (svg-&gt;png): Add 'em' and 'ex' to the 'let-values'
form to account for all the values returned by
'rsvg-handle-get-dimensions', which Guile 2.2 does not truncate.
