Fix htab_delete loop counter
dlclose can crash or stuck the system:
When calling dlclose() then system can crash or freeze, because
htab_delete() in ldso/ldso/fdpic/dl-inlines.h uses size_t for i which
is a typedef to unsigned int. We exit the loop on negative value of i
which can never occur since i is an unsigned int. This leads to random
free of various pointers that kill the system.
* ldso/include/inline-hashtab.h (htab_delete): Change type of 'i' to int.
