Add the swap-modules-rpi3 package build for 32-bit arm

Currently, only arm64 build for rpi3 is supported, but rpi3
kernel also support 32-bit arm. To support the 32-bit kernel,
add the swap-modules-rpi3 package build for 32-bit arm.

Note: new arm built rpm is named with arm arch name because
already existing arm64 built, arm repackaged rpm file name has
aarch64 arch like swap-modules-rpi3-aarch64.

ktd: Fix synchronization when module is unloaded

Problem:
  When unloading the module there was a race condition between
  __put_task_strcut() handler call and cleaning td struct
  for all tasks (after swap_ktd_uninit_top() and
  before swap_ktd_uninit_bottom() calls).

Solution:
  Add get_task_flag flag to td struct. Set it if task was catched
  (increment task usage in swap_ktd_uninit_top() and task_prepare()).
  Add checking this flag and it handler to do_put_task() handler.
