patches: Fix ioctl signature in function definition

patches: Fix ioctl signature in function definition

The `ioctl()` function signature was changed to use an unsigned long as
a second argument, in order to match the definition in Linux, glibc and
our own implementation.
The function definition however was not changed, leading to build errors
due to function signature conflict.
