description:
Add new test file t_ptrace_amd64_wait.c and refactor t_ptrace_*wait* tests

Clone t_ptrace_wait.c to t_ptrace_amd64_wait.c and put common parts to
t_ptrace_wait.h.

The t_ptrace_amd64_wait.c file is dedicated to hold amd64-specific tests
for the ptrace(2) interface.

Add new basic test dbreg1 in t_ptrace_amd64_wait{,3,4,6,id,pid}:
    Verify plain PT_GETDBREGS with printing Debug Registers

Fix evbarm64-aarch64 issue pointed by <christos>, kill1 and kill2 tests
must be defined without PT_STEP guards.
