content/local: inline sys.StatATimeAsTime()

thaJeztah · thaJeztah · commit 63c185da9ad3 · 2021-06-22T10:14:29.000+02:00
The sys.StatATimeAsTime() utility is currently only used in a single place,
but because it's living in the "sys" package, also brings in other dependencies,
such as Microsoft/hcsshim.

This patch inlines the code from sys.StatATimeAsTime(), to remove that dependency.
