Make guality.h handle Yama restricted ptrace mode
guality.exp is silently skipped on Linux systems with
kernel.yama.ptrace_scope=1 because gdb fails to attach to the
sanity check test. This patch uses PR_SET_PTRACER (where available)
to avoid this.
prctl was apparently added in Linux 2.1.57, so I don't think we
need any tests other than __linux for the #include.

* gcc.dg/guality/guality.h: Include <sys/prctl.h> on Linux targets.
