chromium: Reduce minimum browser window width to 480px

The TST043015CNHX panel is a 480x272 panel. Chromium browser limits the
minimum window width to 500px since commits:

6b0ecc1e4532c ("Set lower bound on contents pane size.")
580d6900dc7fc ("In tab dragging, the window size should be larger than its minimum size.")

To make chromium browser usable on those tiny panels as well, reduce
the minimum window width to 480px. The upstreaming of this change is
in progress.
