UAPI: elf_read_implies_exec() is a kernel-only feature - so hide from userspace
elf_read_implies_exec() is a kernel-only feature as the second parameter is a
constant that isn't exported to userspace. Not only that, but the
arch-specific overrides are not exported either.
So hide the macro from userspace.
Similarly, struct file should not be predeclared in userspace.
