[PATCH] sstatesig: Log timestamps for hashequiv in reprodubile builds for do_package

["Richard Purdie" <richard.purdie@linuxfoundation.org>]

Currently if a task generates the same output with different timestamps,
hasequiv won't detect it but reproducibile builds will fail tests due
to the different timestamps.

Add do_package timestamps to the hash when reproducibile builds are enabled
to avoid this.
