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. Fixes #51
