Today, Wine uses NtQueryInformationProcess/ProcessDebugPort to detect
whether the current process is being debugged.  If it is, the process
issues a breakpoint to yield control to the debugger.

Some debuggers (e.g. latest CDB) appear to create debug handles with
restricted DACL, which causes querying debug port to fail with
STATUS_ACCESS_DENIED.  This results in the debuggee erroneously
skipping the initial breakpoint.

Fix this by not requiring DEBUG_ALL_ACCESS when opening the debug port
object.  Instead, use MAXIMUM_ALLOWED for the access mask.
