Subject: [PATCH] hwcontext_vulkan: guard unistd.h include

win32 typically doesn't have unistd.h, so always including it will break
MSVC builds. The usage of those POSIX functions are already guarded by
_WIN32, so use that to guard unistd.h include as well.

(cherry picked from commit 185871fdd39762295973c1f3db1459e04121317c)
