debugging: add calls to 'personality'
Insertion of calls to personality for the only pupose to be able to set breakpoint at some strategic places. The chosen places are: - After the debug wait point. The intend is to allow simulation of breakpoint after attaching to the waiting process. - Before starting the bindings but after loading it. The intend is to allow loading of symbols and setting of breakpoints in the debugged binding without attaching to afb-daemon that comes without debug symbols.
