Revert "Implement basename in shell"

This reverts commit 794f0aac869dda034300211e9be45db123d84377.

Conflicts:
	vcsh

Turns out the shell implementation didn't account for trailing
slashes. While, arguably, a proper interactive shell should eat
them before execution anyway, this can also be called in script
context.

This means that

    vcsh clone foo/

made it fail and even after commit 7e33e38a869989d04d12f2ef160d514041eb01e3

    vcsh clone foo//

would have failed.

Revert to safe and time-proven default: Standalone `basename`.
