If the existing proc instance has over-mounted areas, it can be impossible to mount a new /proc instance (look at SB_I_USERNS_VISIBLE for more details). Actually, runsc-gofer needs /proc just to open /proc/self/fd and to read a few generic files, so it doesn't need a proc instance of the target pid namespace. Fixes #8205 PiperOrigin-RevId: 609634818
