Debarshi Ray 5284f875d3 cmd/run: Fix the name of the shell for running commands in containers
For the most part, this fixes a minor cosmetic issue for users, but it
does make the code less misleading to read for those hacking on Toolbx.
Further details below.

Commands are invoked inside a Toolbx from a helper shell invoked by
capsh(1).  Unless capsh(1) is built with custom options, the helper
shell is always bash, not /bin/sh:
  $ capsh --caps="" -- -c 'echo "$(readlink /proc/$$/exe)"'
  /usr/bin/bash

( The possibility of capsh(1) using a different shell, other than Bash,
  through a custom build option is ignored for the time being.  If there
  really are downstream distributors who do that, then this can be
  addressed one way or another. )

Secondly, the name assigned to the embedded command string's '$0' should
only be the basename of the helper shell's binary, not the full path, to
match the usual behaviour:
  $ bash -c 'exec foo'
  bash: line 1: exec: foo: not found

With 'toolbox run' it was:
  $ toolbox run foo
  /bin/sh: line 1: exec: foo: not found
  Error: command foo not found in container fedora-toolbox-36
