[media] bz#75751: Move internal header file lirc.h to uapi/

The file include/media/lirc.h describes a public interface and
should thus be a public header. See kernel bug
https://bugzilla.kernel.org/show_bug.cgi?id=75751 which has
a manpage describing the interface + an acknowledgment that this
info belongs to uapi.
