CMake: Fix vmaf with non-standard locations

The aom_dsp/vmaf.c change is due to vmaf using include/libvmaf as the
reported include dir. This change was also made in FFmpeg's libvmaf file

Tested with vmaf installed to $PWD/vmafinstall with

```bash
PKG_CONFIG_LIBDIR=$PWD/vmafinstall/lib/x86_64-linux-gnu/pkgconfig/ cmake -B bui -DCMAKE_BUILD_TYPE=Release -DCONFIG_TUNE_VMAF=1 -DBUILD_SHARED_LIBS=OFF
make -j -C bui
```

and with find_package(PkgConfig) commented out

```bash
cmake -B bui -DCMAKE_BUILD_TYPE=Release -DCONFIG_TUNE_VMAF=1 -DBUILD_SHARED_LIBS=OFF -DCMAKE_PREFIX_PATH=$PWD/vmafinstall
make -j -C bui
```

and both passed
