libdwfl: Only intern CU when not EOF marker and cuoff points to a DIE.
We need to check the cuoff points to a real Dwarf_Die before trying to
intern the cu with tsearch. Otherwise bogus keys might end up in the
search tree with NULL cus. That will cause crashes in compare_cukey
during next insertion or deletion of cus. We also don't want to insert
the EOF marker and unconditionally tdestroy the lazy_cu_root. The EOF
could be caused by bad DWARF from a bogus agranges entry.

libdwfl: Handle seeing CU EOF marker without any other (real) CU.
intern_cu (and __libdwfl_nextcu) didn't correctly handle immediately seeing
the CU EOF marker. In that case the *nextp pointer (first_cu) returned by
intern_cu is -1. And less_layzy will immediately destroy the found CU node.
So don't use the *found result after calling less_lazy.
Found by afl-fuzz.

Guard against 64bit unsigned wrap around in (int) compare functions.
Dwarf_Adrr and Dwarf_Off are 64-bit unsigned, and comparison functions
used in qsort or tfind return int, it is possible for the difference to
be so large that it wraps around. Make sure to just return -1, 0 or 1
in compare_aranges and compare_cukey.
