layouts make.tcl: platform_punk boot helper - canonical platform-dir names

Add punkboot::lib::platform_punk to the three layout make.tcl copies
(basic, project-0.1, and the modpod-template mirror): an inline copy of
punk::platform::normalize (the boot stage cannot package require) that
folds platform_generic's version-dependent cpu/os aliases
(amd64->x86_64, aarch64->arm64, macos->macosx, macosx arm->arm64) into
the canonical punkshell platform-dir names. The bootsupport/library
path wiring now uses it, so platform-suffixed dirs match the punkbin /
punk::platform canon documented in 'help platforms'.
