time: delete CURRENT_TIME_SEC and CURRENT_TIME

time: delete CURRENT_TIME_SEC and CURRENT_TIME

All uses of CURRENT_TIME_SEC and CURRENT_TIME macros have been replaced
by other time functions.  These macros are also not y2038 safe.  And,
all their use cases can be fulfilled by y2038 safe ktime_get_* variants.
