fix another memory leak

Browse Source 
In sys_early_init(), the values for sysopt.gdbpath and
sysopt.greppath were being assigned by calling dupstr()
without ensuring that a value previously assigned by
dupstr() were free()'d.

Also, the sysopt struct definition is changed to sysopt_s,
not because there's anything wrong with the original
    struct sysopt sysopt;
but because I couldn't convince the debugger to use the
correct thing when trying to track down the leak.
