lineage: Suppress bash related ioctl denials

These denials are only seen when using bash as the default shell:

  W bash    : type=1400 audit(0.0:55): avc: denied { ioctl } for path="socket:[83675]" dev="sockfs" ino=83675 ioctlcmd=0x540f scontext=u:r:shell:s0 tcontext=u:r:adbd:s0 tclass=unix_stream_socket permissive=0
  W bash    : type=1400 audit(0.0:56): avc: denied { ioctl } for path="socket:[83675]" dev="sockfs" ino=83675 ioctlcmd=0x540f scontext=u:r:shell:s0 tcontext=u:r:adbd:s0 tclass=unix_stream_socket permissive=0

Bash calls isatty() here and there, but it's perfectly safe to ignore
under adbd.
