linprocfs and linux_base port upgrade

I have been able to build linux_base in a jail, but I had to turn on a
few sysctl jail knobs on the main host (see more below)

I usually have, in /etc/sysctl.conf:
...

# for the Jails
security.jail.allow_raw_sockets=1
security.jail.sysvipc_allowed=1
security.jail.chflags_allowed=1
...

I think that last error you got has something todo w/ enabling the
chflags sysctl jail.
