classes/uninative: set SSTATEPOSTUNPACKFUNCS[vardepvalueexclude] properly
Append to the value with appendVarFlag() instead of setting it outright,
so that we can also append to it in other places. Accordingly, this
varflag is pipe-separated (since we want to be able to exclude any
string fragment, in this case including the leading space), thus put a
leading pipe character to play nicely with any existing value.
