Remove legacy NEED_CLANG_LINUX_UBSAN_RTTI_VISIBILITY support
...for ASan/UBSan builds using Clang older than current trunk twoards Clang 9,
as announced at
<https://lists.freedesktop.org/archives/libreoffice/2019-May/082654.html> "Re:
[Libreoffice-commits] core.git: The -fvisibility-ms-compat hack is no longer
needed for UBSan on Linux...". (And drop the no longer needed
solenv/sanitizers/asan-suppressions, which people might still reference from
their ASAN_OPTIONS.)
