releasetools: Add --oem_no_mount option. 

We may have devices with OEM-specific properties but without an OEM
partition (e.g. the properties might be set by init based on hardware
SKUs). For such devices, we supply --oem_no_mount to skip mounting the
OEM partition in the updater-script. The option is only meaningful when
-o (--oem_settings) is specified.

  --oem_no_mount

      For devices with OEM-specific properties but without an OEM partition,

      do not mount the OEM partition in the updater-script. This should be

      very rarely used, since it's expected to have a dedicated OEM partition

      for OEM-specific properties. Only meaningful when -o is specified.

      Generate an OTA package that will wipe the user data partition

      when installed.
