Fix -DBENCHMARK_ENABLE_INSTALL=OFF (Fixes #1275) (#1305)

Browse Source 
Otherwise this fails with
```
CMake Error at src/CMakeLists.txt:154 (export):
  export Export set "benchmarkTargets" not found.
```

This is what https://cmake.org/cmake/help/latest/guide/importing-exporting/index.html#exporting-targets
seems to suggest.

While there, really respect BENCHMARK_ENABLE_INSTALL,
BENCHMARK_INSTALL_DOCS shouldn't override it.
