From: Daniel Turull <[email protected]>

epochfile_read() memoizes its result into __CACHED_SOURCE_DATE_EPOCH
via d.setVar(), so its runtime value leaks into the basehash of any
task that calls it, causing a "metadata is not deterministic" error
once SDE_FILE is populated.

Exclude it, since it is not meaningful build metadata.
