cheri: elf: elfptr_t fixes for preinit/init/fini array

According to the ELF spec:

 "Each element of this array is a pointer to a function to be executed
  by the dynamic linker."

 "Note that the address of a function need not be the same as a pointer
  to a function as defined by the processor supplement."

so these should be accessed via uintptr_t type instead of ElfW(Addr).
