configs/{baseline,releng}/build.sh:
Remove `build.sh` scripts. They were deprecated with v47.
archiso/mkarchiso:
Remove all `build.sh` related functionality (i.e. `command_pkglist()`, `command_iso()`, `command_prepare()`,
`command_install()`, `command_init()`, `command_run()`).
Rename `command_build_profile()` to `_build_profile()` to be more in line with the style of the other function naming.
Change `_show_config()` to only print info about the profile and make no more use of parameters.
Remove all help output related to legacy `build.sh` commands.
