Fix typename typo `input_evnet` should be ` input_event`

[hehelego]

The problem

In commit 189bffe047ef78b01f011ef367c7d3d841d06452.
In src/platform/linux/X/input.c:369, the type of ret should be struct input_event * rather than struct input_evnet *.

This causes a incompatible point type error on line 386 when assigning &ev to ret, raising the following compilation error (on gcc 14.1.1)

src/platform/linux/X/input.c: In function ‘x_input_wait’:
src/platform/linux/X/input.c:386:29: error: assignment to ‘struct input_evnet *’ from incompatible pointer type ‘struct input_event *’ [-Wincompatible-pointer-types]
  386 |                         ret = &ev;
      |                             ^
src/platform/linux/X/input.c:406:16: error: returning ‘struct input_evnet *’ from a function with incompatible return type ‘struct input_event *’ [-Wincompatible-pointer-types]
  406 |         return ret;
      |
