base-linux: avoid global ctor in wait_for_exit

Browse Source 
This patch replaces the global '_wait_for_exit_sem' object by a local
static variable, which does not rely on the global ctors. It thereby
fixes the fault_detection test after the removal of the global ctors
execution from core ("base: remove component.cc from core").
