Correct use of cmake and ninja in Build section

Browse Source 
There is no such thing as `-H.`. I am pretty sure the intention was to use `-S.` (which is a default actually).

`-H` is display help. I am not even sure how it works with `-H.`

For ninja, just use `-C`. No need to change directories, which could be confusing later.

Also the lines before for getting source code use literal directory `vulkandriver`,
so use that in the build too. There is zero reason to complicate it, and if somebody
uses different directory, they are smart enough to change things accordingly.

### Build Driver (64-bit, Release)
```
cd <vulkandriver_path>/drivers/xgl
cmake -H. -G Ninja -Bbuilds/Release64
cd builds/Release64
ninja
cmake -G Ninja -S drivers/xgl -B drivers/xgl/builds/Release64
ninja -C drivers/xgl/builds/Release64
```
> **Note:**
* For RedHat 7.x, please use cmake3(>= 3.13.4) instead of cmake.
* For debug build, use `-DCMAKE_BUILD_TYPE=Debug -DLLVM_PARALLEL_LINK_JOBS=2` (Linking a debug build of llvm is very memory intensive, so we use only two parallel jobs).
* For 32-bit build, use `-DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32`.
* For 32-bit build, use `-DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32`, and adjust build sub-directory accordingly (i.e. `Release32`).
* To enable Wayland support, use `-DBUILD_WAYLAND_SUPPORT=ON`.
