Fix: truncate long process names in Glances widget

[sgrtye]

Proposed change

Currently when using the Glances process widget, the process name could overflow given the text is too long, especially on smaller laptops. The screenshot was taken on a 13-inch MacBook in the fullscreen with a reasonable layout standard.

By adding truncate to CSS, it prevents overflow with the maximum information provided. Although there is still a misalignment issue, it is caused by grow and can not be fixed with CSS only.
