externalsrc: Work with reproducible_build
Externalsrc removes do_fetch, do_unpack, and do_patch. The system normally
discovers the correct reproducible date as a postfuncs of do_unpack, so this
date is never found, so it falls back to the default epoch.
Instead we can move the discovery function to a prefuncs on the epoch
deploy task. This task will run before do_configure, and since the source
is already available can run safely at anytime.
