support/testing: test atop with builtin kernel

Use the new builtin armv5 4.19 kernel to test atop.
The atop package cannot be tested using BASIC_TOOLCHAIN_CONFIG because
it needs kernel headers >= 3.14. So use an updated version of it,
copying the config fragment from
support/config-fragments/autobuild/br-arm-full.config
