cmd/dist can't easily hard-code -buildvcs=false because not all versions of cmd/go supported for bootstrapping recognize that flag. However, we don't want to stamp the bootstrap binaries: the stamping is redundant with the VERSION file writted during bootstrapping (which is why it is normally omitted for standard-library packages and commands), and it may also interfere with building the Go repo from a source tarball or zip file. Fixes #54852.
