The testcase gcc.dg/tree-prof/val-prof-7.c includes <strings.h> to get
a declaration of bzero.  This causes it to fail on targets where bzero
(a legacy function removed in the latest version of POSIX) is not
declared in that header; declaring it explicitly in the testcase is
more reliable.  This patch changes the include to an explicit
declaration.

Tested with cross to i686-mingw32 (where the header just includes
<string.h> and does not provide a declaration of bzero).  OK to
commit?

	* gcc.dg/tree-prof/val-prof-7.c: Declare bzero instead of
	including <strings.h>.
