[PATCH] build: check-manifest runs after tests

[Eric Wong <e@yhbt.net>]

And just treat it as a non-fatal nag when checking the rest of the
codebase.  Calling it "check-manifest" as a `make' target
preserves the old behavior, which causes the check to fail
if a file were added to the worktree without changing the
MANIFEST.
