build-pkgs --reuse rebuilds some packages even without source changes. This commit fixes the checksum comparison which was not working correctly for all package paths. Test Plan: Pass: build-pkgs --reuse and no packages were rebuilt Pass: build-pkgs (no packages were rebuilt) Pass: make changes to 1 package and call build-pkgs to rebuild it Pass: build-pkgs --clean (rebuilds all local packages) Closes-Bug: 1999941 Signed-off-by: Luis Sampaio <luis.sampaio@windriver.com> Change-Id: Id93a692f6a69212967453e42809e66595ae01f59
