Title: Avoid overwriting apache module installed into user's libexec dir

I'd like to change the libexec directory which php-build installs apache module with "with_apxs2" options due to avoid overwriting apache module. Then, we can install the module on each version.

```
e.g.) /path/to/phpenv/versions/5.X.XX/libexec/libphp5.so
```
