tests: multi-hosts: Test lease timeout with LV shareable mode

This patch is to test timeout handling after activate LV with shareable
mode.  It has the same logic with the testing for LV exclusive mode,
except it verifies the locking with shareable mode.

  On the host A:
    make check_lvmlockd_idm \
      LVM_TEST_BACKING_DEVICE=/dev/sdj3,/dev/sdk3,/dev/sdl3 \
      LVM_TEST_MULTI_HOST=1 T=multi_hosts_lv_sh_timeout_hosta.sh

  On the host B:
    make check_lvmlockd_idm \
      LVM_TEST_BACKING_DEVICE=/dev/sdj3,/dev/sdk3,/dev/sdl3 \
      LVM_TEST_MULTI_HOST=1 T=multi_hosts_lv_sh_timeout_hostb.sh
