Luet does expect some parameter or it crashes

[msdobrescu]

Luet version:

luet version 0.32.0-g2aa4c8a42ed13682b4820f3ca5e6d2388a5e2c24 2022-05-03

CPU architecture, OS, and Version:

Linux USC 5.15.38-mocaccino #5.15.38-Mocaccino SMP Fri May 13 15:51:02 UTC 2022 x86_64 11th Gen Intel(R) Core(TM) i7-11700K @ 3.60GHz GenuineIntel GNU/Linux

Describe the bug

Luet displays an internal error when run without parameters, as it expects at least one element in the arguments array.

To Reproduce

Run luet without any parameter

luet
panic: runtime error: index out of range [1] with length 1

goroutine 1 [running]:
github.com/mudler/luet/cmd/util.HandleLock()
        /luetbuild/luet/cmd/util/cli.go:67 +0x2d8
github.com/mudler/luet/cmd.Execute()
        /luetbuild/luet/cmd/root.go:122 +0x19
main.main()
        /luetbuild/luet/main.go:10 +0x17

Expected behavior

An user friendly message? A version info or about info? Help info?
Similar to he message when --debug parameter is set alone:
