x86/CET: Add tests with legacy non-CET shared objects
Check binary compatibility of CET-enabled executables:
1. When CET-enabled executable is used with legacy non-CET shared object
at run-time, ld.so should disable SHSTK and put legacy non-CET shared
objects in legacy bitmap.
2. When IBT-enabled executable dlopens legacy non-CET shared object,
ld.so should put legacy shared object in legacy bitmap.
3. Use GLIBC_TUNABLES=glibc.tune.x86_shstk=[on|off|permissive] to
control how SHSTK is enabled.
* sysdeps/x86/Makefile (tests): Add tst-cet-legacy-1,
tst-cet-legacy-2, tst-cet-legacy-2a, tst-cet-legacy-3,
tst-cet-legacy-4, tst-cet-legacy-4a, tst-cet-legacy-4b
and tst-cet-legacy-4c.
(modules-names): Add tst-cet-legacy-mod-1, tst-cet-legacy-mod-2
and tst-cet-legacy-mod-4.
