Subject: [PATCH] Check for file existance in file modification check

We sometimes start health checks before a file is actually written out
by the service. This results in a bash error in the logs. Let's check
the file exists before trying to use it in the health check.

Change-Id: I58815050117af20abc547f46d15073ac0bf8ca74
Closes-Bug: #1824246
