build: support reproducible builds with consistent man pages
Use a consistent date in the generated man pages even if SOURCE_DATE_EPOCH is not set. * Makefile.am: Generate .timestamp in the tarball. * man/local.mk: Pass .timestamp if available to help2man. * man/dummy-man: Don't bother with the year in the stub. Reported in http://bugs.debian.org/806321
