logind: 0% and 100% should be valid for UserTasksMax (#3836)

config_parse_user_tasks_max() was incorrectly accepting percentage value
between 1 and 99.  Update it to accept 0% and 100%.  This brings it in line
with TasksMax handling in elogind.
(cherry picked from commit cb3e4417590196bd30e1b8097348dca6ba34bd15)
