Subject: [PATCH] [Build] Update SLAVE_BASE_TAG and DPKG cache if Debian
 mirrors were changed (#12702)

Why I did it
After #12557 sources.lists are generated.
So we need to recalculate SLAVE_BASE_TAG if mirrors were changed.
Also we need to rebuild DPKG cache in this case.

How I did it
Use generated sources.list for SLAVE_BASE_TAG
Add MIRROR_URLS and MIRROR_SECURITY_URLS to SONIC_COMMON_FLAGS_LIST
