Extend --check-clean (enabled on bots) to verify build commands don't include absolute paths. The non-RBE GCC and MSVC builds still have absolute paths. GCC doesn't have -ffile-compilation-dir so it uses -fdebug-prefix-map, which is not fixable. The MSVC build has absolute path in the toolchain wrappers, which might be fixable.

This directory was taken from a snapshot of flutter/engine/src/build/.
The snapshot was taken with a recursive copy cp -R of the directory from
the flutter repository.
The contents has now diverged significantly from Flutter, and is maintained independently by the Dart team. It is used to support the GN build system.
