generic: Add tests for inode timestamp policy

Browse Source 
The test helps to validate clamping and mount behaviors
according to supported file system timestamp ranges.

Note that the test can fail on 32-bit systems for a
few file systems. This will be corrected when vfs is
transitioned to use 64-bit timestamps.
