Bjørn Forsman 3d4e133e77 parallel: fix calculation of max line length
parallel >= 20200822 uses /bin/echo to calculate the max allowed line
length. Patch it to a correct path, so that it doesn't (silently) fail
and fall back to a low value of 324.

Before:
  $ parallel --max-line-length-allowed
  324

After:
  $ parallel --max-line-length-allowed
  131063

Fixes: 16ca8725ff ("parallel: 20200722 -> 20200822")
