ash: match behaviour of cmd.exe in cd builtin

The Windows API strips trailing dots and spaces from the last
component of a path.  cmd.exe handles this quirk when changing
directory by adjusting its idea of the current directory to match
reality.  The shell in busybox-w32 didn't do this, leading to some
confusion.

Fix the shell's cd builtin so it works more like cmd.exe.

Adds 64-80 bytes.
