x86/cet: Don't disable CET if not single threaded

In permissive mode, don't disable IBT nor SHSTK when dlopening a legacy
shared library if not single threaded since IBT and SHSTK may be still
enabled in other threads.  Other threads with IBT or SHSTK enabled will
crash when calling functions in the legacy shared library.  Instead, an
error will be issued.

(cherry picked from commit 41560a9312ce0ec7203480eef8f865076bff9edb)
