[packages] olsrd: init: for better reuse, make a function out of a procedure get_value_for_entry()

Browse Source 
Later we want to reuse that functionality, to avoid code duplication
we make a function with clean entry and return-codes, so we can do e.g.:

get_value_for_entry "$entry" || continue

which is also better readable.
