[Intel-gfx] lib: Fix out of tree build of version.h

[Joonas Lahtinen]

Currently out of tree build fails because the version.h.tmp is generated
into the source directory instead of the build directory where it is
later looked for. This commit fixes it.

Subject: [PATCH] lib: Fix out of tree build of version.h

Write the version.h.tmp file into the build directory instead of source
directory. This allows out of tree building when those two are not the
same.
