Daniel Bertalan f18e7659a6 DynamicLoader: Ensure that backtrace computation stops at _start ...

If we don't set FP and LR to 0, the Kernel might not stop generating
backtraces when it reaches `_start`'s stack frame, and might continue by
reading garbage memory instead. This leads to a kernel panic, as SafeMem
access faults aren't handled properly in the AArch64 kernel yet.

We might want to ensure that the kernel zeroes out all registers when a
new process is created.
