base: remove Env arg from init_exception_handling

Browse Source 
By supplying only the parts of the Env that are actually relevant for
initializing the cxx heap, we avoid the need for the 'Env' interface.
The patch also moves the call of 'init_ldso_phdr' to the outside
of the cxx library because it does not belong there.
