[aprssig] Correct DIGI path

The Digi sysop.  And it is sent by the digi.  That has been
fundamental to the New-N Paradigm since 2004.  Every digi beacon is
supposed to begin with the recommended number of WIDEn-N hops and the
local ARRL regional path.  FOr example:

W2, ALn-N. stuff....

Means 2 hops using WIDEn-N and that he ARRL section path is ALn-N
(presumably alabama).  That syntax was standardized and should be in
every digi.

If your digi is not doing this, then it is more than half-a-decade out
of date.  See:
