[FFmpeg-cvslog] hwcontext_vulkan: guard unistd.h include

[Benjamin Cheng]

ffmpeg | branch: release/6.1 | Benjamin Cheng <ben at bcheng.me> | Fri Sep 22 12:49:22 2023 -0400| [884a660cae23769d92d533cc1b6232d3cdfbae43] | committer: Lynne

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)
