keys: make the keyring quotas controllable through /proc/sys
Make the keyring quotas controllable through /proc/sys files:
(*) /proc/sys/kernel/keys/root_maxkeys
/proc/sys/kernel/keys/root_maxbytes
Maximum number of keys that root may have and the maximum total number of
bytes of data that root may have stored in those keys.
(*) /proc/sys/kernel/keys/maxkeys
/proc/sys/kernel/keys/maxbytes
Maximum number of keys that each non-root user may have and the maximum
total number of bytes of data that each of those users may have stored in
their keys.
Also increase the quotas as a number of people have been complaining that it's
not big enough. I'm not sure that it's big enough now either, but on the
other hand, it can now be set in /etc/sysctl.conf.
