extensions: use stream9 as builder because of s390x

[jmarrero]

closes #986

[jmarrero]

Looks like we need ubi9 too if we use stream9 to build:

./usr/bin/webserver: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by ./usr/bin/webserver)
./usr/bin/webserver: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by ./usr/bin/webserver)

latest commit works locally for me. If this is fine we should be good to go.
