cheri: elf: change l_entry to be elfptr_t
It is simpler and more consistent to make l_entry a capability throughout instead of leaving it as an address and converting before use: The AT_ENTRY auxv entry is specified to be a capability and a number if internal l_entry usage is simpler if it is elfptr_t. Functions returning a pointer to the user entry are also changed to use elfptr_t.
