This is not particular to the Drupal site but is caused by the hosting (local Vagrant) environment's PHP configuration.

Try increasing these values in php.ini:

upload_max_filesize = 64M 
post_max_size = 64M 
memory_limit = 64M

NOTE: If you are using Webform for anonymous file upload to your site and you are setting high limits on file size like this you are quickly going to fill up a lot of disk space (most likely with spam).

NOTE: After modifying php.ini file(s), you need to restart your HTTP server to use new configuration
