Don't allow FBT to instrument memcpy(). This is a bit lazy, but avoids several panic variations I've encountered. I need to figure out if it is because memcpy() is being substituted by the compiler, or whether there is an undesirable explicit call to memcpy() somewhere in DTrace or its dependencies.
instrumented by FBT. With this change, we can now instrument all remaining function entries in the kernel using FBT and not immediately crash in boring operation.
