The `srv6_encap_src_addr` topotest tries to load sharpd.conf file that
does not exist, which produces the following warning:
```
2025-02-16 09:23:35,151 WARNING: topo: missing config 'r1' for '/media/frr/tests/topotests/srv6_encap_src_addr/r1/sharpd.conf' creating empty file '/etc/frr/sharpd.conf'
```
Since this topotest doesn't actually use sharpd, there's no point in
loading the config file.

It's just annoying when the linter tells to apply the formatting for the code
you didn't touch.

Add a new topotest `srv6_encap_src_addr` which verifies that the
`source-address` command works properly.
