[OE-core] [PATCH 1/5] useradd.bbclass: Strip trailing '; ' in cmd params

[Khem Raj]

When there are more than 1 packages in a recipe requiring useradd
services, they are concatnated and a ';' is inserted just after
each of the users being added by the packages. A situation arises
in cases where this is controlled by PACKAGECONFIG then we add a
';' separator in the USERADD_PARAM value itself for each packagecofig
since we do not know which one will be picked, we end up in situation
where the final string returned from get_all_cmd_params() appears to be

a; ; b; c;

and then the logic which uses these cmds triggers with ';' as separator
but in this case it will fail after executing useradd 'a' because the next
cmd it will call will be just a whitespace

This is highlighted by the systemd patch to add more users as needed
by systemd 229 components.
