ovmf: Fix native build with gcc-12

Host distros have started deploying gcc12 as well e.g. archlinux
this build failure shows up which has been fixed upstream

In function ‘GetAlignmentFromFile’,
    inlined from ‘main’ at GenFfs.c:816:20:
GenFfs.c:545:5: error: pointer ‘InFileHandle’ used after ‘fclose’ [-Werror=use-after-free]
  545 |     Error(NULL, 0, 4001, "Resource", "memory cannot be allocated  of %s", InFileHandle);
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
