redhat/configs: enable KASAN for -debug kernels

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2121357

Upstream-Status: RHEL only

KASAN has been previously disabled for the -rt patch set due to incompatibilities [1].

Further incompatibilities [2] have been addressed [3].

Since KASAN can be required for the safety argumentation we should enable it again.
