plugin: Add 5s timeout to activate request

[nowrep]

Disconnect clients if they fail to respond within timeout.

Closes #148

[GloriousEggroll]

i compile obs-vkcapture as part of obs then just compile the 32 bit package separately.

In order for this to compile correctly I had to change in vkcapture.c:

#include <obs/util/platform.h>

to

#include <util/platform.h>
