ARM: guard masked symbol tables by default
Symbol tables masked with the loadAddrMask create redundant entries that could conflict with kernel function events that rely on the original addresses. This patch guards the creation of those masked symbol tables by default, with an option to enable them when needed (for early-stage kernel debugging, etc.)
