objtool: fix compilation failure with the x32 toolchain
When using the x32 toolchain, compilation fails because the printf
specifier "%lx" (long), doesn't match the type of the "checksum" variable
(long long). Fix this by changing the printf specifier to "%llx" and
casting "checksum" to unsigned long long.
