Re: [PATCH v6 0/2] MR821: Replace obsolete RtlUniform tests that no longer work (currently skipped) since Windows Vista; update RtlUniform impl.

[Jinoh Kang (＠iamahuman)]

Here is an alternative `RtlUniform` implementation:

```
ULONG WINAPI RtlUniform (PULONG seed)
{
    return *seed = ((ULONGLONG)*seed * 0x7fffffed + 0x7fffffc3) % 0x7fffffff;
}
```

The implementation above is equivalent but slightly slower on my x86-64 machine.

```
RtlUniform (Intel i7-1185G7 Tiger Lake, gcc 12.2.1-4.fc36.x86_64, -O2, simple): 5.905s
RtlUniform (Intel i7-1185G7 Tiger Lake, gcc 12.2.1-4.fc36.x86_64, -O2, no div): 5.706s
```
