[U-Boot] [PATCH v2 37/37] binman: Add support for fixed-offset files in CBFS

[sjg at google.com]

A feature of CBFS is that it allows files to be positioned at particular
offset (as with binman in general). This is useful to support
execute-in-place (XIP) code, since this may not be relocatable.

Add a new cbfs-offset property to control this.

Changes in v2:
- Deal with travis's old lz4 version by skipping tests as necessary
- Skip use of cbfstool in tests if it is not available
