[PATCH] osmo-bts[master]: measurement: fix measurement report interval lookup tables

[dexter]

Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/2416

to look at the new patch set (#3).

measurement: fix measurement report interval lookup tables

The measurment reporting interval, generated from the lookup
defind at the beginning of the source code file (*_meas_rep_fn104[])
is off by one, in some case off by 2. This commit corrects the
timing by subtracting 1 or 2 from the respective lookup table.
