Deepa Dinamani 4bfaca4ef8 generic/402: Make timestamp range check conditional
Addition of fs-specific timestamp range checking was added
in 188d20bcd1eb ("vfs: Add file timestamp range support").

Add a check for whether the kernel supports the limits check
before running the associated test.

Based on an off-list discussion, we use a simpler interim approach
until fsinfo syscall would provide fs timestamp limits info.
This isn't perfect, but works for filesystems expiring in 2038.
