Bad file descriptor error with Chrome/Edge 92 dev releases

[tinywrkb]

zyapk v2021.02, Edge Dev 92.0.902.2, Chrome Unstable 92.0.4515.40.

Edge and Chrome are failing to start with the following errors:

[28 zypak-sandbox] Failed to send spawn request to supervisor: Bad file descriptor (errno 9)
[0602/214632.645836:ERROR:scoped_ptrace_attach.cc(27)] ptrace: Operation not permitted (

Debug output for Chrome: chrome-unstable-strace.log

I'm using my own Flatpak packaging for Chrome Unstable and Edge Dev but I'm not doing something special so I expect that the Flathub packaged Chrome stable and Edge beta apps will also break when updated to 92.

Chrome Unstable 92.0.4496.0 and Edge Dev 92.0.891.1 didn't suffer from this issue.

CC @TheEvilSkeleton as this probably will affect com.microsoft.Edge.

@tinywrkb please try the latest commit and see if it works, if so I'll cut a new release soon(-ish) so we can start getting ready for 92's release.

@refi64 thanks, it's now working perfectly with the latest Chrome Unstable and Edge Dev releases.
Kudos for solving this so quickly.
