ringtools/imy: fix duplicate definition of tdma_durations[]
The bug was reported by Vadim Yanitskiy <fixeria@osmocom.org>,
although the present fix is slightly different from the contributed
patch: because main.c doesn't need this tdma_durations[] array
at all, let's simply remove the reference to this array from main.c
rather than turn it into an extern.
I no longer remember my original thought flow that resulted (by mistake)
in tdma_durations[] being multiply defined in main.c and durations.c.
My intent might have been to define all globals in main.c and have
the reference in durations.c be an extern - and I missed that extern -
but without clear memory, I have no certainty. In any case, having
this data array defined in the same module that fills it (durations.c)
is sensible, so let's make it the new way.
