fix(archroot): pass along the real command and argv by the caller

Before modularizing the repo layout, we used m4_include to assemble
together sources into a single file. Now, we properly use a library
layout without assembling multiple files, which means we cannot anymore
rely on BASH_SOURCE inside the library file. Hence, pass along the
actual command and argv from the check_root caller.

Fixes: src: modularize repo layout into a library
