Bryan C. Mills 4dae3bbe0e cmd/go: disallow package directories containing newlines
Directory or file paths containing newlines may cause tools (such as
cmd/cgo) that emit "//line" or "#line" -directives to write part of
the path into non-comment lines in generated source code. If those
lines contain valid Go code, it may be injected into the resulting
binary.

(Note that Go import paths and file paths within module zip files
already could not contain newlines.)

Thanks to Juho Nurminen of Mattermost for reporting this issue.

Fixes #60167.
Fixes CVE-2023-29402.
