[PATCH] uapi: add missing install of sync_file.h

[Emilio LÃpez]

As part of the sync framework destaging, the sync_file.h header
was moved, but an entry was not added on Kbuild to install it.
This patch resolves this omission so that "make headers_install"
installs this header.

Fixes: 460bfc41fd52 ("dma-buf/sync_file: de-stage sync_file headers")

I don't know if this is worth cc'ing stable, the patch has been
there since v4.7. I spotted this while reflecting on Michael's
review[0] on my kselftest series, and he later independently
confirmed so[1].
