[Build] Add the missing debian security mirrors in slave images (#11305) (#11314)

Why I did it
Cherry-pick from #11305

The build below was broken, it was caused by one of the required debian mirror missing.

 libpci-dev : Depends: libudev-dev (>= 196) but it is not going to be installed
 libsystemd-dev : Depends: libsystemd0 (= 232-25+deb9u14) but 232-25+deb9u13 is to be installed
How I did it
Add the missing mirrors for buster and stretch.
