Subject: [PATCH] Fix tst-memstream3 build failure

Add string.h to avoid tst-memstream3 build failure in some environments:

 tst-memstream3.c:32:17: error: implicit declaration of function 'strcmp' [-Werror=implicit-function-declaration]
  # define STRCMP strcmp
                  ^
 tst-memstream3.c:96:7: note: in expansion of macro 'STRCMP'
    if (STRCMP (buf, W("b")) != 0)

Checked on x86_64.

	* libio/tst-memstream3.c: Include string.h.
