binder: Don't include the compat symbols on arm64 binaries

... Since they're not the same when built at 64-bit, and the likelihood
of blobs requiring this are slim to none, just remove them

SurfaceFlinger: Make secure display ifdefs more narrow.

  * apq8084 target hals do not export display attrs
   the same as previous platforms (8974, 8960 etc)
   but continue the use of QCOM_BSP.
  * Due to this difference secure content is non-visible
   on apq8084 platforms because SF pushes the rendering
   to GLES vice the secure buffer of HWC and MDP.
