busybox: nslookup_lede: fix compatibility with v1.25
The ":*" optstring syntax was only recently introduced with BusyBox v1.26, older versions need a corresponding hint in the "opt_complementary" variable to denote flag values that should be stored as llist entries. Add the required opt_complementary entry to fix random SIGBUS, SIGILL or SIGSEGV related crashes on BusyBox 1.25.x when attempting to use the "-q" flag of the "nslookup_lede" applet.
