[Iftop-users] [PATCH] Fix minor ui annoyance when ligatures are suported.

[Ariel Popper]

When `iftop` is run under a terminal/font combination that supports
ligatures, the "<=" characters form a single, stacked "less than or equal to"
glyph rather than an arrow pointing left. This patch replaces "<=" with "<-"
along with some others in order to remain visually consistant.
