hack(6): Fix a segfault that occurs when ASLR is enabled

Prior to this change, savenames() would store "objects" in save files as a
blob, and restnames() would load it and overwrite "objects". But since
objclass::oc_name and oc_descr are pointers to string constants, they would
be invalid when the next time the process is spawned, and opening the
inventory would crash by dereferencing invalid pointers.

Use the right type for the malloc wrapper function, and don't cast the
return value.

(XXX: Except for a pile of allocation macros that produce typed pointer
results; there the typechecking of the result assignment is more valuable
than the warning if the alloc function isn't declared properly. These
macros should go away.)
