[PATCH 1/1] sandbox: compatibility of os_get_filesize()

[Heinrich Schuchardt]

U-Boot define loff_t as long long. But the header
/usr/include/linux/types.h may not define it.
This has lead to a build error on Alpine Linux.

So let's use long long instead of loff_t for
the size parameter of function os_get_filesize().
