[sanitizer] Fix suffix-log-path_test.c on arm-linux-gnu

The recent suffix-log-path_test.c checks for a full stacktrace and
since on some arm-linux-gnu configuration the slow unwinder is used
on default (when the compiler emits thumb code as default), it
requires -funwind-tables on tests.

It also seems to fix the issues disable by d025df3c.
