ldso: make exit condition clearer in fixup_rpath

breaking out of the switch-case when l==-1 means the conditional below
will necessarily be true (-1 >= buf_size, a size_t variable) and the
function will return 0. it is, however, somewhat unclear that that's
what's happening. simply returning there is simpler
