Improve clojure.java.browse (#846)

Browse source 
* Remove xdg-open hardcoded path in impl.clojure.java.browse

Binaries in Linux are not guarantee to be located on /usr/bin.

For example, NixOS the binaries are located in
/run/current-system/sw/bin/xdg-open (that is actually just a symlink to
/nix/store). The distro may also not have xdg-open installed at /,
instead the user may put it somewhere else like $HOME/bin.

This commit fixes this by using not hardcoding the PATH of xdg-open,
instead relying on shell path to search it.

* Implement clojure.java.browse/*open-url-script*

This allows usage of a custom URL script, like:

```clojure
(binding [*open-url-script* (atom "my-browse-url-script")]
  (browse-url "https://google.com"))
```

*open-url-script* is an atom just to keep compatibility with Clojure.

Described here: https://clojuredocs.org/clojure.java.browse/*open-url-script*
