dashboard/config/linux: disable most UBSAN configs
Some UBSAN configs got enabled unintentionally just after olddefconfig.
Disable most of them as they produce lots of crashes.
Keep UBSAN_SHIFT, though, as people seem to fix these reports.
Also change smack instance to clang as that's what we actually use
for the instance. That caused some unwanted diffs in UBSAN configs
as well, as UBSAN checks depend on the target compiler.
