FS#105 - chromium crash in blocked syscalls (libseccomp)

chromium apparently also has trouble in some seccomp jailing:

In the GUI you just get the usual "Aw, Snap!" in a tab.

version 80.0.3987.122 also shows this problem in testing after a rebuild, so it needs
patching the seccomp handling in chromium itself..

firefox also shows seccomp sandbox violations with syscall 403, presumably the same lack
of 32-bit seccomp rules also in firefox. There though the content of the page is shown
(at least for simple examples).
