[PATCH OSSTEST 7/8] Debian: Enable interpolation in uboot_scr_load_dtb here doc

[Ian Campbell <ian.campbell@citrix.com>]

By switching <<'END' to <<END. A future patch is going to want to put
a variable here which requires interpretation by the Perl.

Unfortunately this means lots of extra backticks to escape things such
that they pass through Perl and Shell and end up as ${foo} in the
resulting u-boot script.
