amdfwtool: Add a way to detect the file name with absolute path

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 has a '/', we will treat it as an absolute (to top)
path.
