seabios: Fix malloc_fn function pointer in romfile patch

One of our SeaBIOS patches causes build errors with GCC 15:

  src/romfile.c: In function 'romfile_loadfile_g':

This is because the function pointer defined as `void *(*malloc_fn)()`
refers to a function that takes no arguments, unlike `malloc_tmphigh`
which takes an unsigned int. Add the missing argument type.
