SOURCE_DATE_EPOCH environment variable override the timestamp

This is applying the version 1.1 of the specification (https://reproducible-builds.org/specs/source-date-epoch/)
where the only timestamp that Bazel puts in the final targets is overridden by the value of SOURCE_DATE_EPOCH.

This change also remove the legacy SOURCE_DATE_EPOCH handling which wasn't really following
the spec.

Note that Bazel itself tries hard to remove all timestamps from intermediary binaries and
overridde SOURCE_DATE_EPOCH in most action, which is a not according to the version 1.0 of the spec
but according to the expected change for version 1.1.

RELNOTES: SOURCE_DATE_EPOCH (https://reproducible-builds.org/specs/source-date-epoch/) can
be used to override the timestamp used for stamped target (when using --stamp).

Fixes #2240.
