[collect|ocp] Fix backtrace in ocp collector

While runnng sos collector in an ocp cluster
we got the following trace:

Traceback (most recent call last):
  File "/usr/sbin/sos", line 22, in <module>

        line 81, in oc_cmd
    'which oc', chroot=self.primary.host.sysroot
TypeError: run_command() got an unexpected keyword argument 'chroot'

This patch changes the unused option 'chroot' that was undefined in
run_command() to the option need_root that was in use in other commands
in ocp.py.
