runtime: pass through -asan/-msan/-race to testprog tests

The tests using testprog / testprogcgo are currently not covered on the
asan/msan/race builders because they don't build testprog with the
sanitizer flag.

Explicitly pass the flag if the test itself is built with the sanitizer.

There were a few tests that explicitly passed -race (even on non-race
builders). These tests will now only run on race builders.

For #71395.
