Added "no-emit-version" to default GnuPG configuration
Disabled build-time fetching of PGP keys

Now always using bundled PGP keys.
Minor fresh build fixes

Now using latest-stage3-i686.txt instead of latest-stage3.txt that
might include only 486 images due to Gentoo stage3 issues.

Restored fetch of stage3-i686-*.tar.bz2.CONTENTS since it is listed
in signed stage3 digests.

Added /tmp/.private append-only flag removal to "mkroot" (as it is
already being done in "setup").
