sdm660-common: rootdir: ueventd: Make all mem_buf VM files read-only for all

Browse source 
The mem_buf VM files under /dev/mem_buf_vm/ are only ever opened with
O_RDONLY permissions.  Additionally, processes not in the 'system'
group need to be able to open the mem_buf VM files.  Correspondingly,
make the permissions for all of these VM files 444.
