Commit 38765ab68f moved the bzero, bcopy, and explicit_bzero
fortified macros to a common header (strings_fortified.h). However
the side effect is a fortified explicit_bzero is defined when including
only strings.h.
This patch moves back the fortified explicit_bzero definition to
strings3.h header.
Checked on x86_64-linux-gnu.
* string/bits/strings_fortified.h (explicit_bzero): Move back to ..
* string/bits/string3.h: ... here.
