temp/gtk+3.0: update version to purism's 3.24.37-2pureos3
This fixes a number of bugs (including #2211 (closed) and #2210 (closed)) and brings us the last two years of updates.
The three patches we were applying are all already applied in the commit to which we update, so drop them from the package.
Closes #2211 (closed), #2210 (closed)
