nfsd: remove NFSD_V4_DELEG_TIMESTAMPS Kconfig option
Now that there is a runtime debugfs switch, eliminate the compile-time
switch and always build in support for delegated timestamps.
Administrators who previously disabled this feature at compile time can
disable it at runtime via:
echo 0 > /sys/kernel/debug/nfsd/delegated_timestamps
