Remove PR_TAGGED_ADDR_ENABLE from sys/prctl.h
The value of PR_TAGGED_ADDR_ENABLE was incorrect in the installed headers and the prctl command macros were missing that are needed for it to be useful (PR_SET_TAGGED_ADDR_CTRL). Linux headers have the definitions since 5.4 so it's widely available, we don't need to repeat these definitions. The remaining definitions are from Linux 5.10. To build glibc with --enable-memory-tagging, Linux 5.4 headers and binutils 2.33.1 or newer is needed. Reviewed-by: DJ Delorie <dj@redhat.com> (cherry picked from commit f4596d9540021265a99697fceef8a434c47e8bcf)
