Used by http_dav_module instead of nginx-dav-ext-module about nginx-builder

Hello! You should install both modules: ngx_http_dav_module and nginx-dav-ext-module.
config.yaml

nginx_version: 1.14.0
output_package: rpm
modules:
  - module:
      name: http_dav_ext_module
      git_url: https://github.com/arut/nginx-dav-ext-module.git
      git_tag: v3.0.0
      dependencies:
        - libxml2-devel
        - libxslt-devel
  - module:
      name: http_dav_module
      type: embedded

And you missed brace in webdav.conf
