selinux - allow dnsmasq to getattr on fifos

This is presumably libc isatty detection on stdin/out/err.
Either way - allowing it is harmless.

This fixes:
  type=1400 audit(): avc: denied { getattr } for comm="dnsmasq" path="pipe:[38315]" dev="pipefs" ino=38315 scontext=u:r:dnsmasq:s0 tcontext=u:r:netd:s0 tclass=fifo_file permissive=0

Test: built and observed no more avc denials on crosshatch
