Enable setting a fixed font for 'wine' in test/handle_keys.cxx

Browse Source 
... w/o editing a file. The default font is "Liberation Mono".

Just set environment variable FLTK_USING_WINE=1 to enable this feature.

Rationale: on /my/ current test system the font chosen by `wine` for
FL_COURIER is a proportional font whereas the display in Fl_Terminal
requires a fixed font for correct output. Font "Liberation Mono"
solves this long standing issue for me w/o having to change source code
but other Linux systems may require a different font.
