Add missing permission for accessing the DMA-BUF system heap
This patch fixes the following denials:
avc: denied { open } for comm="composer@2.4-se" path="/dev/dma_heap/system"
dev="tmpfs" ino=700 scontext=u:r:hal_graphics_composer_default:s0
tcontext=u:object_r:dmabuf_system_heap_device:s0 tclass=chr_file permissive=1
