Two things:

a) glissandoMap has to be set _before_ the note/chord from which the 
glissando starts

b) (0 . 0) (0 . 0) doubles the glissando from the first chord note to 
the first chord note. If you want "parallel" glissandi (first note to 
first note, second note to second note), take (0 . 0) (1 . 1).

Leading to:

\version "2.20"

{
  \once \set glissandoMap = #'((0 . 0) (0 . 1))
  \once \hideNotes <d, g >8 \glissando <a' e'>2.
  \once \set glissandoMap = #'((0 . 0) (1 . 1))
  \once \hideNotes <c g >8 \glissando  <a e'>2.
}  %m1
