Dominique Martinet abc0a7bdac mcs_rwlock: remove aligned(64) attribute if ENABLE_UBSAN ...

The attribute would impose 64-bytes alignment that we do not
respect later because the whole structures (e.g. process/thread)
are allocated at 32bytes boundaries with kmalloc

These are however justified for performance reason as we do not want
them on same page cache line, so just accept slower performance for
UBSAN only
