[OE-core][PATCH] package_rpm: set clamp_mtime_to_source_date_epoch to 0

[OE-core][PATCH] package_rpm: set clamp_mtime_to_source_date_epoch to 0

[Bin Lan]

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

This change sets clamp_mtime_to_source_date_epoch to 0 in do_package_rpm() to remove the warning.

Please ignore this patch. I will investigate it again.

But does this change introduce issues? This was originally set for a
reason, what was the reason? Should it be replaced with
built_mtime_policy as suggested?
