When using binman with the '-a spl-dtb=y' flag, if the SPL blob is not
found, binman throws a cryptic error message:
binman: 'NoneType' object has no attribute 'startswith'
Let's improve the error message to explicitly state which SPL blob is
missing.
This is particularly useful when binman is used as a standalone tool
outside the U-Boot source tree.
