build fails: pango_cairo_font_map_set_default() not declared

After the commit:

commit 35643d86af5f41011723c7363172628283c0b96d
    wxt: release per-thread font data structures before forking

build fails on my Mac (with clang) as:
wxterminal/wxt_gui.cpp:3868:3: error: use of undeclared identifier 'pango_cairo_font_map_set_default'

We need to include <pango/pangocairo.h> either in wxt_gui.cpp (as in
the patch below) or in wxt_gui.h (whichever you prefer).
