maint: Cater for running `make dist' from a tarball.

Browse source 
* Makefile.am: Use in_git_p conditional to disable Autotools' cache
consistency assert and removal when bulding from tarball.
(dist): Depend on doc-pot-update again when building from tarball.
(dist-hook): Remove dependencies on gen-ChangeLog and gen-AUTHORS when
building from tarball.
(gen-ChangeLog, gen-AUTHORS): Remove guarding for building from tarball.
Use set -e to avoid silently failing.
(gen-tarball-version): Use $(SOURCE_DATE_EPOCH) instead of re-generating it
using git; this also works running from a tarball.
