package_rpm: set a timestamp handling policy with the new macro %build_mtime_policy

There is the following warning when the do_package_write_rpm task is executed
when bitbake linux-yocto:
  warning: %clamp_mtime_to_source_date_epoch is deprecated, please use %build_mtime_policy

After RPM is upgraded to 4.20.0, the %clamp_mtime_to_source_date_epoch macro is
now deprecated in favor of %build_mtime_policy set to clamp_to_source_date_epoch.
