bsc: TC_paging_imsi_load: retransmit 'no paging buffer space'

If 5 seconds expire, the BSC will automatically re-fill a credit
of 20 paging slots [to work with BTSs where the paging buffer space
indications somehow are missing].  Let's make sure we don't hit
that case, even if the operating system sleeps for more than 5s
in this test .
