In an attempt to support 64 bit time handling before the linux
kernel developed time64_t and ktime lustre attempted to use
64 bit jiffies with a libcfs abstraction. Lets remove these
wrappers and replace them with modern 64 bit time support. The
lustre code that used these wrappers needs time resolution at
the seconds level so replace the code with time64_t handling.

WC-bug-id: https://jira.whamcloud.com/browse/LU-9019
Lustre-commit: 2728de4db8c0 ("LU-9019 libcfs: remove cfs_time_XXX_64 wrappers")
