linux/time.h: Add Linux time conversion defines

Currently there are no defines for time conversion in time.h, which
leads to drivers declaring those locally or not using defines at all, so
add them from Linux.

lib/date: Make rtc_mktime and mktime64 Y2038-ready

We currently overflow due to wrong types used internally in rtc_mktime,
on all platforms, and we return a too small type on 32-bit.

One consumer that directly benefits from this is mktime64. Many others
may still store the result in a wrong type.

While at it, drop the redundant cast of mon in rtc_mktime (obsoleted by
714209832db1).

linux/time.h: include vsprintf.h

Without this commit, time.h possibly causes a build error as
asctime_r() uses sprintf().

lib: add mktime64() for linux compatibility

This function will be used in lib/crypto/x509_cert_parser.c, which
will also be imported from linux code in a later commit.

linux/time.h: Remove dead code

Since
rem = ((long) *tim_p) % SECSPERDAY;
the second while cycle
while (rem >= SECSPERDAY)
is dead.
