[ng] dist: remove workaround needed by BSD make only

* am/lib/configure.am (distcheck): GNU make (without the '.ONESHELL'
special target specified, which we don't support anyway) is assured
not to re-use the same shell in different commands of the same recipe,
so we can slightly simplify our rule accordingly, removing workarounds
that were only relevant fr BSD make when run in parallel mode.
