syscalls: wrap personality syscall if undefined 
There's no need to making personality handling conditional as it has
been around for such a long time that only weird systems wouldn't have
support for it. And especially if the user requested a specific
personality to be set but the system doesn't support the personality
syscall we should loudly fail instead of moving on.

72f83931b3 github: remove the dh-* packages 
We don't build any packages there so it seems we don't need
those packages any more. Apart from that, it should make the
script work on Ubuntu Hirsute where dh-systemd was merged into
debhelper and is no longer available.

lxc_monitord: remove monitord log 
The tool is effectively unused with current master so removing the log
should be ok by now. Let's remove the log to avoid issues such as #3747.

cgroups: fix fallback attach codepath 
When we attach to an old server the server can return ENOSYS instead of
ENOCGROUP2 which causes LXC to abort the attach unnecessary. Fix this!

a390325fdf oss-fuzz: always turn off logging on OSS-Fuzz 
Apparently /proc/self/cmd can't be used (reliably) on OSS-Fuzz to figure out
whether the code is run inside the fuzz targets, which causes the
fuzz targets to fill the filesystem with log files.
