bts_tests: do not define bs_ag_blks_res in multiple locations

The parameter bs_ag_blks_res is currently defined in ts_SI3_default and
in each PagingTestCfg record. When the parameter is changed in
PagingTestCfg it must be changed in ts_SI3_default as well in order to
have coherent settings in the stestsuit and in the BTS. This can be
quite confusing so lets use the setting from ts_SI3_default when
populating PagingTestCfg to have the value of the constant in one place
only.
