Update the new C and asm interrupt return code to account for 64e
specifics, switch over to use it.
The now-unused old ret_from_except code, that was moved to 64e after the
64s conversion, is removed.

Then ACCOUNT_CPU_USER_EXIT can be removed from asm/ppc_asm.h
And all associated definitions in asm-offsets.c
And also ACCOUNT_USER_TIME which was likely left over after the removal of
ACCOUNT_CPU_USER_ENTRY()
