metee: Fix build failure with musl libc

Add patch to fix sign-conversion warnings with musl ioctl macros.
musl's ioctl request macros expand to unsigned long values, causing
sign-conversion warnings when passed to ioctl() which expects an int.

Cast the macros explicitly to int in three ioctl calls:
- IOCTL_MEI_CONNECT_CLIENT
- IOCTL_MEI_CONNECT_CLIENT_VTAG
- IOCTL_MEI_NOTIFY_GET
