gnu: gtk+: Fix build on i686-linux.

Looks like the (graft) update to gtk+ to 3.24.49 never built on i686-linux due
to a failing test.  It is unclear why, but since we use an old librsvg on this
platform compared to x86_64, that is a major difference in the build/tests.

* gnu/packages/gtk.scm (gtk+)[arguments]<#:phases>: Skip the linear-gradient
on i686-linux.
