lib: Add SPDX identifiers to files missing them

This adds SPDX identifiers to the remaining source files in the
lib directory that don't already have them.

A note on gcov-iov.h - As machine generated content, this file is
believed to be uncopyrightable, and therefore in the public domain, so
gets the CC-PDDC license even though there is code in the file.
