[Impact]
* An error message is included in when rendering landscape-sysinfo
statistics through pam_motd if there are processes with a non-ascii
command. This is due to the fact that environment is not passed
by pam-motd.
* As landscape-sysinfo is present on cloud-images, this bug affects
all images since bionic.
* This change sets locale variables in the landscape-sysinfo wrapper,
so the python interpreter can know which locale to load.
[Test Case]
* Make sure the system default locale is configured with a valid
charset (e.g. /etc/default/locale contains "LANG=C.UTF-8").
* Spawn a process with non-ascii parameters (which are part of the
configured charset): sh -c 'sleep 60; echo holà mundo' & sudo login
* Check the output of the motd
[Regression Potential]
* Since this changes only alters the landscape-sysinfo wrapper script,
its effects shouldn't alter other functionalities.
* Although it is still possible to have a misconfigured locale file,
and run commands, the effect would be limited to an error message
similar to the one which is currently displayed.
