Troubleshooting mode (syslinux): stop passing options that can only break stuff

See merge request !2

With "nomodeset", GDM disables Wayland, but we only support Wayland,
so this cannot possibly work.

And I don't think vga=normal (which is about old-school video framebuffer) is
going to help a DRM driver set up graphics.

Fix including local packages.

See merge request !1

Previously, including packages in config/chroot_local-packages would
break the Tails build.  The reason is that the version of live-build
used by Tails tried to create an OpenPGP key to sign the local
packages, but that key creation was designed with GnuPG 1.4.x in mind.
With 2.x, GnuPG tries to invoke a pinentry tool to ask for a
passworod, which failed likely due to stdin not being connected to a
terminal.

This patch drops the key generation, and instead marks the local apt
repository as trusted.  This is what contemporary versions of
live-build do.

Fixes tails#15618

Exposing exposes the SOURCE_DATE_EPOCH variable when running scripts inside the chroot, otherwise the chroot operation resets the environment (Closes: #833118).

This is needed to generate reproducible images when using the S_D_E
patchset for libisofs and libisoburn.

Setting xorriso's "modification time" to SOURCE_DATE_EPOCH as a first step for reproducible ISO images (Closes: #832689).

Gbp-Dch: Ignore

Use xorriso instead of genisoimage, by backporting (most of) lb_binary_iso from live-build 5.x at commit 3c303e7f.

Note that we don't import the latest version, that introduces more
changes we won't focus on right now (multi-bootloaders and EFI support).

Adding LD_PRELOAD and FAKETIME to the list of variables passed through to commands run with Chroot().
