    firmware-utils: seama.h: replace LGPL-2.1-or-later boilerplate with SPDX
    
    This was missed because scancode license scanner was confused by a
    slightly different than expected license text (96,75% license score).
    
    License text included "file" instead of "library" in the main part of
    the licensing info. It also used "The GNU C Library" instead of the
    standard "This library" in 2nd and 3rd paragraphs.
    
    The first paragraph clearly mentions LGPL-2.1-or-later and the use of
    "file" instead of "library" should not affect licensing.
