Ensure MIN/MAX are defined in userspace builds of rx

The include of <sys/param.h> was removed from rx_packet.h on
Linux 2.6 and later to fix kernel builds with 3.7, which doesn't
have that header in kernel space.  However, while kernel space
always provides MIN/MAX defines, userspace relied on the header.
On at least powerpc, no other include chain includes sys/param.h,
so MIN/MAX were left undefined.

Fix this by only skipping the include of <sys/param.h> on Linux
if building in kernel mode.
