www/qt5-webengine: fix build with libc++ 17
Building www/qt5-webengine with libc++ 17 results in the following
compile errors:

This is because perfetto's CircularQueue template is only half
const-correct. Upstream fixed this in:
https://github.com/google/perfetto/commit/b82a213bcf71dd8e68b53941375936c7905c0ff2
so apply that fix to qt5-webengine's older copy of perfetto.
