Update debuggerd for stack MTE.
Two things need changing for debuggerd_test to pass.
1. The seccomp policy needs to allow for PROT_MTE (0x20) in both
mprotect() and mmap(). Stack MTE processes do a mprotect()/mmap() of
the stack when launching a process.
2. The fault address and stack pointer need to be untagged when trying
to figure out the stack overflow cause.
