rc.inet1*: Simplify virtif_* code, add note to example config

There is a built-in way of counting the number of elements in an array:
${#arrayname[@]}. Use this, and the fact that "for i in $(seq 0 -1)" will
not evaluate body of the loop even once, to simplify code and get rid of
virtif_determine().

While at it, add a note to rc.inet1.conf mentioning the necessity of
keeping array indexes monotonically increasing (from 0), otherwise the
code will fail (so would the original code).
