patch: Make sort-test handle more then 100 lines, and avoid segfault

[Petter Reinholdtsen <pere at hungry dot com>]

The sorting test is at the moment unable to handle tests with more the
100 lines, because of a typo in the calculation of nstrings_max.  This
patch move a parentheses to it's correct location.  It also add
argument checking, to avoid segfault if the required first parameter
is missing, and free the malloc()ed memory to make it easier to spot
errors using valgrind.

Please include the change in the next version of glibc.

	* collate-test.c (main): Correct handling of files with more then
	100 lines. Print error message if argument is missing, instead of
	segfaulting.  Avoid memleak in test code.
	* xfrm-test.c: Likewise.
