[snap] The SUID sandbox helper binary was found, but is not configured correctly.

[Alex Muntada]

The chromium snap version 1260 has the wrong mode for chrome-sandbox, as it happened also in bug #1854091:

```
$ /snap/bin/chromium
[4009:4009:0809/115259.781182:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /snap/chromium/1260/usr/lib/chromium-browser/chrome-sandbox is owned by root and has mode 4755.
Trace/breakpoint trap
$ [4134:4134:0100/000000.834554:ERROR:zygote_linux.cc(653)] write: Broken pipe (32)
```

I have reverted it to the previous version (1244) and this one works (and has the right mode for chromium-sandbox).

That's suspicious, can you please share the output of `ls -l /snap/chromium/current/usr/lib/chromium-browser/chrome-sandbox` ?

Is the latest update (revision 1269) similarly affected?

The current version (1284) works OK and the SUID bits are back:

```
$ ls -l /snap/chromium/current/usr/lib/chromium-browser/chrome-sandbox
