Replace firmware build time with epoch

Using __DATE__ and __TIME__ causes cache-misses / reproducibility
issues and the only use of this function is when acquiring the firmware
build time.

In OpenWeave, the firmware build time is used as a fallback mechanism if
the real clock time cannot be acquired. However, this implementation
only exists in OpenWeave's CASE delegate, which is overriden by
Fuchsia's platform implementation in //src/connectivity/weave, so it is
not actively used today.

In general, we do not want CASE operations to be load-bearing on the
build date, so we opt to remove this logic and always return the epoch.
