BTS_Tests: fix both TC_si_sched[_13_2bis_2ter]_2quater

The current definition of the SI2quater Rest Octets is incomplete.
In particular, the missing part is Repeated UTRAN FDD/TDD Neighbour
Cells structure, for which 3GPP came up with a very tricky encoding.

Given that both test cases checking scheduling of the SI messages
and not their content, let's simply use different SI2quater samples
containing E-UTRAN Parameters Description instead.
