libsdl2: disable shared memory for native builds

Browse Source 
libsdl2 currently does not handle the failures that
occur due to shared memory in case of remote hosts
where it should ideally switch to socket based writing
when a failure is seen with shared memory.
Consider a scenario where a qemu build is done with
graphics support on a build machine and then accessed
remotely using ssh. If the remote host's X presents
MIT-SHM as an extension, launching qemu fails with

runqemu - ERROR - Failed to run qemu: X Error: BadValue
Request Major code 130 (MIT-SHM)
Request Minor code 3 ()

This is most often seen when the remote machine doing
ssh is a Ubuntu 20.04. The libsdl2 native are mainly
used for qemu at this time so it is a major usecase.
A report of such a failure was also presented at
https://lists.yoctoproject.org/g/poky/topic/78854857
