staging: android: ram_console: honor dmesg_restrict
The Linux kernel has a setting called dmesg_restrict. When true,
only processes with CAP_SYSLOG can view the kernel dmesg logs. This
helps prevent leaking of kernel information into user space.
On Android, it's possible to bypass these restrictions by viewing
/proc/last_kmsg.
This change makes /proc/last_kmsg require the same permissions as
dmesg.
