[ubsan][test] Don't disable ubsan testing on 64-bit Solaris/x86

[ro]

Summary

Unlike asan, which isn't supported yet on 64-bit Solaris/x86, there's no reason to disable
ubsan. This patch does that, but keeps the 64-bit ubsan-with-asan tests disabled.

Tested on x86_64-pc-solaris2.11. Ok for trunk?

[ro]

Ping? It's been a week now and it should be pretty clear that 64-bit Solaris/x86 asan support is immaterial for ubsan.
