refactor: rename custom/ to installer/ for clarity

The custom/ directory name was an archiso implementation detail. Renamed
to installer/ which clearly communicates that this directory contains the
installer scripts and utilities that ship on the ISO.

Updated all references in build.sh, Makefile, test-install.sh, and README.
