docs: Add list of C source files instead of calculating it using 'find'.

Add the real list of C source files to the Makefile, instead of trying
to calculate it.  This (will, in the next commit) fix a problem with
the build on Koji where we created a subdirectory (for python3/) but
the find command picked up files from that directory for the
documentation (and then failed).

This fixes commit 04229c68d6.
