Log Message:
Add new tests dbregs_dr[67]_dont_inherit_lwp in arch/amd64

New tests:
 - dbregs_dr6_dont_inherit_lwp
 - dbregs_dr7_dont_inherit_lwp

Debug Registers are set always per-LWP and they are never inherited.
If a user wants to reuse them, there is need to set trap on thread creation
(PTRACE_LWP_CREATE) and set them from a debugger on newly created LWP.
