drisw: Fix build on Android Nougat, which lacks shm (v2)
In commit cf54bd5e8, dri_sw_winsys.c began using <sys/shm.h> to support
the new functions putImageShm, getImageShm in DRI_SWRastLoader. But
Android began supporting System V shared memory only in Oreo. Nougat has
no shm headers.
Fix the build by ifdef'ing out the shm code on Nougat.
Fixes: cf54bd5e8 "drisw: use shared memory when possible"
