Subject: [PATCH] sdksyms.sh: don't embed the build path

This script generates a header that has a comment containing the build path for
no real reason.  As this source can end up deployed on targets in debug packages
this means there is both potentially sensitive information leakage about the
build environment, and a source of change for reproducible builds.
