cmd: setexpr: add format string handling
Add format string handling operator to the setexpr command.
It allows to use C or Bash like format string expressions to be
evaluated with the result being stored inside the environment variable
name.
setexpr <name> fmt <format> [value]...
The following example
setexpr foo fmt "%d, 0x%x" 0x100 ff
will result in $foo being set to "256, 0xff".
