Remove ASan option detect_odr_violation=0 from libshortfin CI

[marbre]

ODR violations are ignored by setting ASAN_OPTIONS=detect_odr_violation=0, which was done in the CI workflow .github/workflows/ci_linux_x64_asan-libshortfin.yml with PR #152. This option should be removed asap.

It the option is set in the CI since the target shortfin_array_test fails during compilation with
