spkg-check.in: Remove messages that duplicate sage-spkg's messages

[mkoeppe]

build/bin/sage-spkg already does:

        echo "Running the test suite for $PKG_NAME..."

and

            if [ "$SAGE_CHECK" = "warn" ]; then
                error_msg "Warning: Error testing package $PKG_NAME (ignored)" "make check"
            else
                error_msg "Error testing package $PKG_NAME" "make check"
                exit 1
            fi

So we remove the messages printed by individual spkg-check.in.

Depends on #29492
