vk_image.c: #ifndef _WIN32 --> DETECT_OS_LINUX + DETECT_OS_BSD

DRM modifiers are a BSD/Linux phenomenon.

We can also remove a bunch of these checks too.  No Linux specific
symbol or header is **actually** used, and the DRM modifier is
just represented as uint64_t.  But kept the style of the file
as is.
