[dpdk-web] [PATCH] fix navigation bar with fallback font

[Thomas Monjalon <thomas.monjalon@6wind.com>]

When the font exo2 is not available (because of disabled download),
the fallback font can be too big and make the menu oversized on
two lines.
The fallback font size is adjusted thanks to font-size-adjust
property. It is supported only on Firefox.
