Fix Coverity Scan build target

When PR #1271 was merged (commit c34c8db4), it:

 1. Created a new coverity-build target in src/Makefile
 2. Updated .github/workflows/coverity.yml to call make coverity-build
 3. Forgot to add coverity-build as an explicit target in the top-level Makefile

This commit also simplifies src/Makfile a lot for readability.
