[U-Boot] [PATCH 20/34] binman: Allow symbols to be resolved inside sections

[sjg at google.com]

At present we only support symbols inside binaries which are at the top
level of an image. This restrictions seems unreasonable since more complex
images may want to group binaries within different sections.

Relax the restriction.

Also fix a typo in the comment for testTpl().
