ash: Remove unused EV_BACKCMD flag
The original ash defered forking commands in backquotes so builtins
could be run in the same context as the shell. This behavior was
controlled using the EV_BACKCMD to evaltree.
Unfortunately, as Matthias Scheler noticed in 1999 (NetBSD PR/7814),
the result was counterintuitive; for example, echo "`cd /`" would
change the cwd. So ash 0.3.5 left out that optimization.
