[OE-core] [PATCH 1/1] rpm_4.14.0: clamp timestamps by default

[Juro Bystricky]

Improve reproducibility by making sure that timestamps
in built rpms are not later than the value of SOURCE_DATE_EPOCH as
found in the environment.
Timestamps as usual when SOURCE_DATE_EPOCH is not set.

[YOCTO #12425]
