bsc: allow individual T_guard timeout via f_init()

The TC_ho_neighbor_config_* tests sometimes take longer than 30 seconds,
because they run multiple handovers. Since they don't have access to the
Test_CT, they cannot restart the T_guard. The simplest solution is to choose a
longer T_guard timeout for those tests specifically, by adding an argument to
f_init(). (A longer timeout for those tests is following in another patch.)

Why f_init()? Assigning a different default value to T_guard seems to not be
possible, but a different timeout value can be passed to T_guard.start(), which
happens in f_init().
