With the previous logic, the legacy PTP instances could get created much
after update/upgrade procedure ran if the host was configured with
clock_synchronization=ntp during those procedures, but then changed to
ptp later on.
This change introduces a flag in the file system telling the
update/upgrade procedure actually ran and shouldn't run a second time
even the legacy instances were not created and host changed to be
ptp-synced.
Test Plan:
PASS: Upgrade from r/stx6.0 to r/stx7.0 (master), w/o configured PTP;
PASS: Upgrade from r/stx6.0 to r/stx7.0 (master), w/ configured PTP;
PASS: Patch apply then removal on r/stx6.0, w/o configured PTP;
PASS: Patch apply then removal on r/stx6.0, w/ configured PTP;
PASS: Upgrade from PATCHED r/stx6.0 to r/stx7.0 (master).
