conformtest: Update expectations for time.h

[Joseph S. Myers]

Continuing the review of conformtest data for ISO C standards, this
patch updates the data for time.h to correspond more accurately with
C90, C99 and C11 and to use conformtest features to describe as many
requirements of the standards on that header as possible.  Tested
x86_64.

This completes updating for ISO C standards the data for headers
present in C90.  I think the next step will be C90 Amendment 1 support
for conformtest, and updates for the headers added in C90 Amendment 1,
so that conformtest then completely covers everything from
stdlib/isomac.c.

	* conform/data/time.h-data (NULL): Use macro-constant.  Require
	equal to 0.
	(CLOCKS_PER_SEC): Use macro instead of constant.  Specify type as
	clock_t.
	[ISO11] (TIME_UTC): Use macro-int-constant.  Require value > 0.
