On bullseye, the following build command does not fail when configure
step is failing:

```
stepanb@3012cc6b379a:/sonic/src/sonic-sairedis$ fakeroot debian/rules binary-syncd
...

On previous buster, however, this command fails as expected:

```
stepanb@99083f3297fd:/sonic/src/sonic-sairedis$ fakeroot debian/rules binary-syncd
...

stepanb@99083f3297fd:/sonic/src/sonic-sairedis$ echo $?
```

It is required to have -e in .SHELLFLAGS to fail on such errors.

This change also fixes pysairedis install files.
