Fix an overlap between two elements of the Image form input.

Summary:
The filename field and the checkbox to select the default image were
overlapping in Firefox on Linux on both the Project Edit page and the
Profile Edit page.

Test Plan: Looked at both of the pages and saw that they rendered better.
