dbus-manager: fix tainted string

Browse Source 
The pointer to the end of the string was not advanced after adding
the "cgroups-missing" taint. If "local-hwclock" was detected too,
it would overwrite the previous string.

With 'e' always pointing to the end of the string, removing the last
delimiter is easier.
