[ubsan] Add preinit initializer for ubsan
Summary:
Now that ubsan does function interception (for signals), we
need to ensure that ubsan is initialized before any library
constructors are called. Otherwise, if a constructor calls
sigaction, ubsan will intercept in an unitialized state, which
will cause a crash.
This patch is a partial revert of r317757, which removed
preinit arrays for ubsan.
