kexec_file: increase maximum file size to 4G
In some case initrd can be large. For example, it could be a netboot
image loaded by u-root, that is kexec'ing into it.
The maximum size of initrd is arbitrary set to 2G. Also, the limit is not
very obvious because it is hidden behind a generic INT_MAX macro.
Theoretically, we could make it LONG_MAX, but it is safer to keep it sane,
and just increase it to 4G.
Increase the size to 4G, and make it obvious by having a new macro that
specifies the maximum file size supported by kexec_file_load() syscall:
KEXEC_FILE_SIZE_MAX.
