BSC_Tests_CBSP: fix f_exp_rsl_etws(): add some guard time
Recently I noticed sporadic CBSP test case failures on Jenkins:
Timeout waiting for RSL_OSMO_ETWS_CMD (disable)
BSC_Tests_CBSP.ttcn:1209 BSC_Tests_CBSP control part
BSC_Tests_CBSP.ttcn:1056 TC_cbsp_emerg_write_bts_cgi_cchan_disable
The related timeout is set to 5.0 seconds in f_exp_rsl_etws(), what
matches the Warning Period IE sent in CBSP WRITE-REPLACE message.
Adding a debug log printing T.read on receipt of RSL_OSMO_ETWS_CMD
reveals that we're cutting it too close: the message arrives just
a few milliseconds before the timeout expires.
f_exp_rsl_etws(): T := 4.999196s, remaining 0.000804s
f_exp_rsl_etws(): T := 4.998683s, remaining 0.001317s
f_exp_rsl_etws(): T := 4.999344s, remaining 0.000656s
Let's increase the timeout value (+0.5s) to avoid sporadic failures.
