FIP tool: Fix error message for missing FIP filename

Browse Source 
Previously to this path, the FIP tool used to print the following,
misleading error message when called without any argument or with
'--help' option:

  ERROR: Too many arguments

This patch fixes this behavior by printing the following error
message instead:

  ERROR: Missing FIP filename

If called with '--help', no error message is printed and only the
help message is displayed.
