Fix Neutron precheck to not fail with newer Docker

Browse Source 
With newer Docker versions `systemctl show docker` returns:

  MountFlags=shared

Instead of:

  MountFlags=1048576

This fix accepts either value as valid to ensure the check is not
erroneously failing.

Closes-Bug: #1791365

# When MountFlags is set to shared, a signal bit configured on 20th bit of a number
# We need to check the 20th bit. 2^20 = 1048576. So we are validating against it.
# In some systems MountFlags on the Docker service is set to 'shared', whereas
# in others it's set to the decimal value of the 20th bit. This now checks for both
# values. Either '1048576' or 'shared' will pass the precheck.
