From: Stephen Warren <swar...@nvidia.com>
Update the common Tegra boot scripts in the default environment to
a) Make use of the new "test -e" shell command to avoid some error
messages.
b) Allow booting using the sysboot command and extlinux.conf. This
allows easy creation of boot menus, and provides a simple interface
for distros to parameterize/configure the boot process.

v4:
* Prioritize extlinux.conf over boot.scr.uimg when searching; it makes
sense to use the cross-distro/-bootloader (hopeful) standard first.
* Replace ; in the middle of echo'd text in boot scripts.
* Add missing space between commands in boot scripts.
* s/exists/test -e/ in commmit description.
v3: s/exists/test -e/ in shell commands.
v2: No change.
