amdfwtool: Detect the file name with absolute path in fw.cfg

Here is the example to add a file which is not in the default path.
--------------
XXXXX_FILE 3rdparty/blobs/mainboard/google/guybrush/TypeId0xXXX.sbin
----------------
If the filename in fw.cfg contains a '/', we will treat it as an
absolute (actually relative to top) path.
