Eina: sanitize eina_path output on Windows

Summary:
 * remove additional \ character
 * use only / as path separator

Test Plan:
compilation and run

test program :

```
{
        elm_app_bin_dir_get();
        printf("%s\n", eina_vpath_resolve("(:tmp:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:home:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.desktop:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.documents:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.downloads:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.music:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.pictures:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.public:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.templates:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.videos:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.data:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.config:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.cache:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.run:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:usr.tmp:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:app.dir:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:app.bin:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:app.lib:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:app.data:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:app.locale:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:app.config:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:app.local:)/foo"));
        printf("%s\n", eina_vpath_resolve("(:app.tmp:)/foo"));
    }
