camera/media: Support legacy HALv1 camera in mediaserver

Pre 7.0 camera HALv1 can not share its video buffers
across different processes, which requires us to
disable this security feature.

This change allows devices to re-integrate cameraserver
and mediaserver which is the first step to support older
prebuilt camera HALs. A follow-up change will add back
support for legacy buffer handling.

To enable:
TARGET_HAS_LEGACY_CAMERA_HAL1 := true
media.stagefright.legacyencoder=true
media.stagefright.less-secure=true

Change-Id: I4fcc8907ea235b7e83af26122b4da97ca5117816

mediaserver: Update HALv1 dependencies for 8.1.0

 * Add libcameraservice shared library dependency
 * Add new libgui, android.hardware.camera.common@1.0
    and android.hardware.camera.provider@2.4 shared
    libraries and exported headers HAL dependencies

 * Match cameraserver HIDL additions and dependencies

 * When TARGET_HAS_LEGACY_CAMERA_HAL1 is set, the mediaserver
    includes CameraService.h but exported headers are missing

 * Error upon build due to missing libcameraservice linkage:
    fatal error: 'android/hardware/BnCameraService.h' file not found

mediaserver: Update HALv1 dependencies for 9.0.0

 * Disable active state UID validation for HAL1 devices
