Instead of passing a /proc/self/fd bind mount we use --bind-fd, which has two advantages: * bwrap closes the fd when used, so it doesn't leak into the started app * bwrap ensures that what was mounted was the passed in fd (same dev/ino), as there is a small (required) gap between symlink resolve and mount where the target path could be replaced. Please note that this change requires an updated version of bubblewrap.
