[Buildroot] [PATCH] package/radvd: drop dependency on flex runtime library

[Alexander Mukhin]

Radvd has its own main(), and does not use yywrap() from libfl.so,
because scanner.l module contains noyywrap option. So, none of the
functions exported by libfl.so are used, and there's no need to have
the flex runtime on target.
