fix: send implicit_mod to process_bindings (#176)

* fix: send implicit_mod to process_bindings

this solves the edge case where someone might have `ShiftMask + A` in
their keybindings compared to a plain `A`.

Closes: https://github.com/nsxiv/nsxiv/pull/166#issuecomment-978853136

* code-style: smuggle small style fix in

win_draw_bar now mimics autoreload_nop.c functions
