Another missing HEAPALLOC

BUG: permanent allocation in getstrvalue
~zs

PERMALLOC is set in bin_cd for calling cd_get_dest(), but the
parameter code in getnamedir() needs HEAPALLOC.  (Is this
getstrvalue() test new?  I've only just started noticing the error
messages.)  The following patch is chosen simply to make the minimum
code reorganisation necessary, but maybe the HEAPALLOC needs to be
further down in getstrvalue() or wherever, as Zoltan suggested.
